Estimation of Spectral Resolution of Imaging Spectrometers from Fraunhofer Lines with the MODTRAN Atmospheric Model

— A technique is suggested for estimating the spectral resolution of video spectrometers in separate sections of the sensitivity scale via comparison of experimental survey results with model (calculated for the same observation conditions) Fraunhofer lines from a set of preset values. The maximal e...

Description
Summary:— A technique is suggested for estimating the spectral resolution of video spectrometers in separate sections of the sensitivity scale via comparison of experimental survey results with model (calculated for the same observation conditions) Fraunhofer lines from a set of preset values. The maximal estimation errors of the technique suggested are within 0.5 nm at the considered test lines 700 and 587 nm for both mass-produced spectroradiometers and original video spectrometers.
