Full Scene Selected Zoomed ROI
Multiple Fisheyes for Full Surround View
A Staring Full Scene Imager with Simultaneous Optical ZoomFor Surveillance and Tactical Applications
Janet E. Shields and Richard W. JohnsonScripps Institution of Oceanography, University of California San Diego
Multiple Fisheye systems with zoom for full sky and terrainSupplement existing optical and acoustic sensors
TanksFull Surround View
Using multiple lenses
Vehicle remains buttoned up while viewing full surround.User actively chooses area to zoom.Minimizes laser eye safety issues
SurveillanceFor military and civilian
Threat-sensitive Sites
Motion Detection enables automated designation of ROIAutomatically controls alarms and peripheral sub-systems
Littoral ZoneCovert Surveillance
Moored system deployedBy covert insertion vehicle
Unattended Ground Sensors
Three images would be combined electronically for full scene view.Any image could be zoomed using prisms to select scene in near-real-time.
Two or three fisheye lensesWith prisms to image full surround
Mockup forConceptual Evaluation
ProprietaryU. S. Patent PendingUCSD 2003-249
Full Scene: Optical Resolution Target in Lab Full Scene Radiometrically Enhanced to Show Resolution Target Partial Optical Magnification of Fisheye’s Image Plane Close-up of the Optically Zoomed Target ImageHigh Optical Magnification of Fisheye’s Image Plane
A Novel System (patent pending) to enable Covert, Fast Surveillance
One or more 180 degree lenses monitor the full surround
Novel optics are used to magnify the image plane
A high resolution view of a selected ROI is created
The full scene view and zoomed ROI are shown simultaneously
Concept is in development stage
All significant elements have been tested in mock-up configuration
A Full Scene view and Magnified ROI are shown simultaneously
Target image from a single fisheye lens is split to create two identical image planes
One image plane is shown in full scale
Second image plane is imaged again with magnifying optics
Magnifying optics retains detail (high spatial frequency) lost in normal electronic zoom
ROI designated interactively or automatically
Rotating Dove prisms enable fast selection of region for zoom
Readily Adaptable for Multiple Applications
Can monitor complete surround, unlike mechanical zoom lenses
Robust and covert: no external moving parts
Retains detail lost in electronic zoom
Can respond to user interaction or motion detection algorithms
Can be developed potentially for daytime, nighttime, visible, or IR
Can automatically control alarms and peripheral subsystems
Prisms are used to create two image planes.One is used for behind-the-lens zooming.
User simultaneously views full field and selected region.

Multiple Dove Prisms are used for fast imaging of Region Of Interest
