Abstract

The spatial-temporally modulated imaging spectrometer obtains two dimensional spatial images modulated by interference fringe, whole interference fringe of the given target extracted by plenty of images, so it is highly sensitive to the stability of platform. The corner cube mirror could improve the spectral range of the imaging spectrometer, especially the mid and far infrared. The blur of interference fringe by corner cube mirror vibration across and along its axis is analyzed, displacement of interference fringe is mainly caused by corner cube mirror moving along its axis, the stability of installation in this direction must be ensure.
