Characterization helps in evaluating design performance and specifying instruments based on requirements
Suggested specification that each imager should aspire to give the user:
Architecture of the spectrometer: Diffraction, Prism, etc.
Number of Pixels / Spatial Resolution (columns and rows)
Spectral Range (ex: 400 to 1100 nm) – usable range
Signal-to-Noise over the Spectral Range
Spectral Sampling / Number of bands (ex: 5 nm/140 bands)
Spectral Resolution / Spectral Bandwidth
Radiance Responsivity (W/sr-m2-nm)/(counts/sec)
Radiometric / Wavelength Accuracy over full range
Smile & Keystone, PSF
