Summary
The Face2Phase conference presents research that make use of phase information, namely
Holography, Tomography, Phase Retrieval and their applications. Its goal is to let students
who are studying in this research topic gain more ideas about the cutting-edge technology
and get some insights about the application in industry. The conference also provides the
interaction between researchers working in these fields, in particular, interaction between
young and more experienced researchers. The conference received great success, with 9 invited talks, 24 contributing talks, and 17 poster contributions.
Apart from the already mentioned Holography Exhibition, a student event on Monday is organized by the SPIE Student Chapter of Delft University of Technology and sponsored by SPIE. The topic of Face2Phase is arguably the most important property of any optical field, namely its phase. With information about the phase of an optical field one can see in three dimensions, i.e. one can see that objects are situated behind each other. Attendees can even look around corners, as is convincingly demonstrated by the impressive holograms in the Holography Exhibition held in the same building as the conference. The importance of lensless imaging and computational optics are rapidly growing as soft x-rays, for which high quality components do not exist, are increasingly used in applications, e.g. in lithography for ICs. During the conference the SPIE FOCUS logo is always presented in the front of the venue, hence SPIE received great acknowledgement from the audiences.

Invited Speakers 5. Prof. Mitsuo Takeda, Untsunomiya University, Japan
The first invited talk is given by Prof. Mitsuo Takeda. The title of the talk is ‘Marriage between holography and statistical optics for unconventional imaging: coherence holography and holographic correloscopy’. Traditionally, holography and statistical optics have been regarded as mutually separated fields of optics. He talks about introducing some of their recent efforts to bridge the gap between the two fields, which resulted in unconventional imaging techniques called coherence holography and holographic correloscopy.
6. Dr. Andreas Menzel, Paul Scherrer Institure, Switzerland
The second invited talk is from Dr. Andreas Menze. He talks about their recent development in X-Ray ptychography.
The unavailability of highly resolving, efficient, and aberration-free X-ray optics gave rise to the development of “lens-less” microscopy techniques applicable to X-ray imaging. Among a variety of coherent diffractive imaging (CDI) techniques, which offer high resolution at high dose efficiency, ptychography has been found particularly robust and reliable and has been made available at numerous user facilities worldwide.
Invented in the 1960s in the context of electron microscopy, ptychography comprises sampling and analyzing the object’s spatial spectrogram by windowed (or “short-space”) Fourier transforms. An analytic solution to the inversion problem exists in the form of the so-called Wigner distribution deconvolution. However, this particular approach is subject to experimentally rather forbidding sampling requirements. More relevant in praxis are therefore iterative reconstruction techniques that allow for significantly sparser sampling and allow for simultaneous reconstruction of both object and illumination, i.e., the Fourier transform’s window function. Recent algorithmic developments can further yield three-dimensional information from essentially two-dimensional measurements or allow for deviations from “ideal” measurements conditions.
Instrumentation, reconstruction techniques, and applications will be discussed, in particular regarding opportunities at upcoming sources which, compared to today’s sources, will increase the usable flux by orders of magnitude.

7. Prof. Martin J. Booth, University of Oxford, UK
Prof. Martin J. Booth gives us an overall introduction to Adaptive optics in nanometer scale.
Adaptive optics (AO) has been introduced into microscopes to overcome the problems caused by specimen-induced wavefront aberrations. This is particularly important when focusing deep into tissue where the cumulative effect of focusing through the refractive index structure of the specimen causes significant wavefront distortion. These AO systems employ a dynamic element, such as a deformable mirror or spatial light modulator, to correct aberrations, restoring image quality. Adaptive optics has been demonstrated in a range of microscope modalities including conventional widefield microscopes as well as laser scanning systems with various applications in biomedical imaging and other areas. Adaptive microscopy has most recently been developed for super-resolution microscopes – or nanoscopes – which enable resolutions smaller than the diffraction limit of light. He reports on a range of recent advances in this field.
8. Prof. Bahaa Saleh, University of Central Florida, USA
Prof. Bahaa Saleh gives us a talk on how to measure the phase information using Quantum-enhanced technology.
A principal question in optical interferometry, which is an established tool in metrology, is the precision of phase measurement. The accuracy of phase estimation is limited by shot noise, which is particularly manifest when weak light sources are used. Light probes in nonclassical states, for which the photon number statistics are sub-Poisson, or the photons
10
are in an entangled quantum state, have been shown to surpass the Heisenberg limit of precision. However, this super-sensitivity is often accompanied by enhanced vulnerability to noise and decoherence within the system itself. As an example, in two-photon interferometry, the slightest amount of decoherence can cause total loss of phase sensitivity at certain values of the interferometer phase difference. This talk begins with a tutorial overview of quantum-enhanced interferometric phase measurement techniques and their limitations. He then introduces the notion of ancilla-aided interferometry – the use of a probe with an ancillary degree of freedom, such as polarization. He shows that when the ancilla and the normal interferometer path degrees of freedom are entangled, and with appropriate measurements at the output end of the interferometer, the quantum super-sensitivity that has been diminished by decoherence, can be restored.
9. Prof. John Rodenburg
Prof. John Rodenburg of University of Sheffield, UK is one of the pioneers in the field of X-ray imaging. His introductory talk is about the accurate, self-calibrating phase imaging.
Once seen as an obscure solution of the diffraction plane phase problem, ptychography has evolved with extraordinary speed over the last ten years. It should be seen as a very general computational imaging technique that relies on encoding optics (whether via a diffraction pattern or an image), translational diversity and a decoding algorithm. The range of optical set-ups that can exploit these concepts is large. Because the information diversity can be vast, the method can self-calibrate, removing a wide class of experimental errors including those of the encoding optics themselves, errors in the translation vectors, errors in the detector and its position, and partial coherence in the illuminating beam. Its first major application area was in X-ray imaging, but it is now making in-roads into visible and EUV light imaging and electron imaging.

10. Dr. Roarke Horstmeyer, Humboldt University of Berlin, Germany
Dr. Roarke Horstmeyer presents a method to boost the resolving power of current
microscopes to one gigapixel using a technique termed Fourier ptychography. No moving
parts or precision controls are needed for this resolution enhancement. The only required
hardware is a standard digital microscope and an array of illumination LEDs, while an
optimization algorithm does the rest of the work. This talk also describes an extension of
Fourier ptychography that can create 3D volumetric images of thick specimens, and discuss
the various challenges associated with imaging highly scattering samples.
11. Malgorzata Kujawinska, Warsaw University of Technology, Poland
Prof. Malgorzata Kujawinska gives us a talk about recent development on Holographic
microscopy and tomography in the field of biomedical applications
Label-free quantitative phase imaging techniques are becoming increasingly important and
popular in biological and medical applications. It is due to their capability of measurement
and monitoring of cells with absolute biophysical parameters like optical path length delay,
volume, refractive index or dry mass without affecting normal cell functions or disturbing
proliferation. Digital holographic microscopy (DHM) is currently the most adapted and
precise measurement method when applied to semitransparent and purely phase biological
samples such as living cells and microorganisms. It is also the best method to provide input
12
data for accurate optical diffraction tomographic (ODT) reconstruction of 3D refractive index
distribution.
In the talk, at first, the state-of the-art in the field of digital holography and 3D phase imaging
techniques is presented. Next the recent advances in tomographic measurement, numerical
approaches, algorithms and architectures of holographic data capture will be discussed.
Special attention is given to novel schemes of modulation of an object illumination beam,
numerical focusing, aberration compensation and holographic data manipulation for both full
and limited projection angle tomography. New measurement scenarios and algorithms for
limited angle tomographic reconstruction based on generalized total variation iterative
constraint strategy and extension of depth-of-field will be introduced. Some interesting
examples of DHM and ODT implementation in biomedical investigations will be presented.
Finally, the challenges connected with the necessity to improve spatial resolution of DHM and ODT and to develop holographic systems for digital pathology is discussed.
12. Wolfgang Osten, University Stuttgart, Germany
Prof. Wolfgang Osten gives us the talk about Exploiting the whole information content of the light field: limitations and approaches.
In the context of measurement technology, optical methods have a number of unique features.
To them belong in particular the non-contact and high-speed interaction with the object
under test, the largely free scalability of the dimension of the probing tool, the high resolution
of the data, the diversity of information channels in the light field, and the flexible adaptability
of the comparative standard. On the other hand, the user is also confronted with a bunch of
challenges. Here one should mention especially the indirect nature of the measurement. This
fact is the origin of a number of serious consequences which make it often difficult for the
practitioner to decide for optical metrology. However, the numerous information channels
recommend optical principles for the solution of various inspection and measurement
problems. A broad variety of techniques is sensitive for the measurement of a particular
quantity such as the intensity, the frequency, the phase, the angular spectrum, the
polarization state, the angular momentum, the degree of coherence and the time of flight. By
applying these methods, a wide spectra of spatial, spectral and temporal modalities can be
evaluated. To them belong dimensional, structural, geometrical, colorimetrical, chemical, and
mechanical properties of the object under test. More modern principles such as hyper-
spectral technologies are designed to measure various modalities with one system. Known
under the name of multimodal measurement techniques, these systems are capable of
13
elegantly solving complex medical, structural-mechanical or biological problems. However,
the high information density in optical signals is often not only an advantage but a challenge
with respect to the correct interpretation of the measured data. This talk starts with a brief
summary of the advantages and disadvantages of optical metrology. Afterwards he discuss
the various information channels and present examples for their exploitation. Special attention is directed to the correct interpretation of the data.
13. Allard Mosk, Utrecht University, The Netherlands
Prof. Allard Mosk’s talk is about light in scattering medium. Random scattering of light, which
causes the opaqueness of paper, paint and biological tissue is an obstacle to imaging and
focusing of light. At the same time scattering is a phenomenon of basic physical interest as it
allows the study of fascinating interference effects such as open transport channels, which
enable lossless transport of waves through strongly scattering materials. The transmission of
these open channels remains high even for a thick sample, while their statistical occurrence
offers a new way to measure the scattering strength of a material. Individual open channels
can be elucidated by repeated phase conjugation, and this opens them up to detailed
spectroscopy measurements, allowing space-time mapping of these remarkable transmission
properties in three-dimensional optical systems.

Contributing Speakers We have in total 24 contributing talks from all over the world, including our chapter member Hai Gong. Below are summary of part of the interesting talks.
Hai Gong, Delft University of Technology, The Netherlands. Shack-Hartmann wavefront sensor based phase microscopy.
He is currently a PhD student of DCSC in Delft with the research background of optical sensing.
In the talk he talks about measuring the quantitative phase by a Shack-Hartmann wavefront
sensor. And when the spatial coherence condition is satisfied that the numerical aperture of
the illumination should be smaller than the numerical aperture of the imaging lens.
The phase or optical path difference of the microscopic sample provides plentiful information
about the sample, such as creating good image contrast in the transparent and translucent
cases and characterizing the profile of the surface in reflective cases. Comparing with the
holographic or interferometric methods, the SH technique needs no delicate reference beam in the setup, which simplifies the system.
Larry X.-C. Yuan, Shenzhen University, China. Optical communication using singular optical
beams
Prof. Larry X.-C. Yuan currently works at Shenzhen University. He has a very strong research
background in vectorial beam shaping and optical communication. In his talk he introduces the research carrying on in his research team.
Singular Optical beams such as orbital angular momentum (OAM) beam and cylindrical vector
beam (CVB) have shown advantages in increasing the data transmission rate in both free-
space optical and fiber optical communication systems. Here, we will review several singular
beams based optical communication techniques developed by our research group. I. Massive
individual OAM channels multiplexing enabled by a Dammann optical vortex grating with sub-
Pbit/s data rate. II. CVB multiplexing communication in few mode fiber. III. Integrated OAM
(de)multiplexer with high efficiency and broad bandwidth. The singular beams based optical
communication techniques have the potential for the next generation high performance
computing applications.

Esteban Vera, Pontificia Universidad Catolica de Valparaiso, Chile. Simultaneous compressive imaging with phase aberrations
Dr. Esteban Vera is an associate professor from Pontificia Universidad Catolica de Valparaiso.
He gives an interesting talk on compress imaging technique. They present a new approach for
snapshot compressive imaging by engineering a point spread function using optical
aberrations. Compressive imaging simulation and experimental results at 16x compression,
using both natively sparse and natural scenes, demonstrate the enhanced ability of aberrated
imaging systems to compress images.

SYSTEM DESIGN IN INDUSTRIAL
INNOVATION. Without proper insight in market mechanisms, the marketplace can be
experienced as chaotic and hostile. Competition is intense and
increasing in speed. New technologies are appearing on every field. For
many companies the struggle is how to navigate, how to keep up with
the speed of innovation, how to stay agile and effective. Is there order
in this chaos?
Focus in this talk is on the role of the designer-engineer in the practice
of research and development of advanced complex systems in an
industrial environment. Where do innovation ideas come from and how
to be stubborn and listen at the same time.

A true leader knows that information is essential to take the best
decisions. But sometimes the right information is difficult to find or
even to read. In this talk I will talk about the importance of keeping an
open and inquisitive mind. I will illustrate it with my own experience
moving from being an experimental Physicist to work as Patent analyst.
I will share how Patents can be used to keep track of the newest
scientific and technological developments and at the same time
motivate the creativity. I will close by explaining how to identify the
relevant information in a Patent in a fast and efficient way.
