Abstract

This paper describes a method of modeling and testing of a modular imaging spectrometer instrument (MISI), with special emphasis on system and sub-system modulation transfer function (MTF) analysis. The optical system was modeled using optical ray tracing methods. The dynamic deformation of the scan mirror was modeled using a finite element analysis method, and the image degradation due to the deformation is estimated using optical image formation theory. The detector and conditioning electronics were also modeled using the transfer function theory. This modeling approach was used as a tradeoff tool for the design of MISI. Laboratory experiments were conducted to test the performances of each sub-system on design criteria, and finally a field test is planned to test the overall optical/mechanical/electrical performance of the entire imaging chain.
