Paper Abstract

A preliminary investigation on interferometry for space-borne atmospheric sounding is shown in this paper. It includes design, optical implementation subsystem and the testing results of the model instrument. The experiment scheme characterizes an amplitude-splitting two-beam interference, time modulation, driving reflector directly by a linear motor and reducing tilt influence using a pair of corner reflector. The reference signal is produced by He-Ne laser beam. The optical sounding wave bands with the preliminary model are 7.5-15μm. Experimental results showed that spectrum resolution is about 2 cm-1. In addition, a further study program is also presented in the paper, which will result in a space-borne atmospheric sounding interferometer after several years. Now the program is under way. As its first step a study is made on some basic problems and on some comparisons among different designs for interferometers: translation corner reflector type, swing plane mirrors type.
