SPECTRAL IMAGING

5

SPECTRUM Spectrum is defined as the intensity of light as a function

of wavelength

It can be presented for example as:

Emission spectrum

Reflectance spectrum

Absorption spectrum

Transmission spectrum

Material dependent

Due to the molecular structure

Photons are absorbed and this causes rotation and vibration of water molecules (heating the sample)

WHAT IS HYPERSPECTRAL IMAGING ?

7

Purpose of Spectral Imaging

Spectral Imaging is used to detect individual material-dependent features or “fingerprints” due to specific chemical bonds in different materials.

The ultimate goal

Complete spectrum is collected at every position of the samples

Detect different materials - Qualitative and Quantitative analysis

Spectral and Spatial distribution

HOW TO PRODUCE HYPERSPCETRAL DATA

PUSH-BROOM APPROACH

www.specim.fi

A line-scan device

Full spectra of the all spatial positions along the imaged line is recorder in one single snapshot

Target must be imaged line-by-line to form the 2D image

PUSH-BROOM APPROACH

www.specim.fi

Pushbroom is the preferred technology selection for most spectral imaging applications

Pushbroom technology provides ca. 5-10 times higher light throughput than tunable filters

Illumination can be focused 10-30 times more efficiently

On-line application Need for simultaneous spectral data in each pixel with a moving

target or moving instrument Moving webs and conveyer belts

Same technology in outdoor measurements, laboratory and final application

WAVELENGTH RANGES
