Abstract

Experimental results are described from a pushbroom imaging spectrometer module demonstrating very low spectral and spatial distortion (a few percent of a pixel) and similarly small variation in spectral response function with field position. These spectrometer properties significantly facilitate the extraction of accurate spectroscopic information. The spectrometer can achieve high performance despite relaxed tolerances in fabrication and alignment. A quick and effective alignment method is described that permits the spectrometer to approximate its design performance. The implications of the results for the calibration techniques of pushbroom imaging spectrometers are also discussed. © 2000 Society of Photo-Optical Instrumentation Engineers.
