Designing for Optimum Response in a Pushbroom Spectrometer

A method of designing a compact pushbroom imaging spectrometer includes explicit consideration and minimization of nonuniformity of spatial and spectral response. It appears that prior to the development of this method, the issue of nonuniformity of response was addressed haphazardly. The major advantage afforded by the present method is that it enables systematic optimization of the smallest possible pushbroom spectrometer within a given class of spectrometer designs.
