Paper Abstract

Spaceborne Fourier transform spectrometers (FTSs) are one of the most promising sensors for global measurements of the atmosphere and/or the surface because of its potentialities for high spectral resolution and high accuracy. One of the difficulties for realizing a high performance FTS is how to overcome its performance degradation caused by disturbances such as mechanical vibrations and shocks. We have developed a computer-based simulator to evaluate the performance degradation. Influence of vibrations for various kinds of FTSs using different optical elements and different sampling methods are examined by evaluating spectral measurement errors quantitatively. It is shown that spectral measurement errors of FTSs is restrained by using corner cube reflectors and sampling method defined by laser interference.
