ABSTRACT:
A continuous drive type Michelson interferometer system for use in Fourier spectroscopy, having a main Michelson interferometer for obtaining the interferogram of a sample, an auxiliary Michelson interferometer for detecting the moving speed of a movable mirror of said main Michelson interferometer, and a control section for controlling the driving speed of said movable mirror. In said control section, the AC output signal of a photodetector is converted into a voltage corresponding to the frequency of the signal, said voltage is compared with a preset voltage by a voltage difference detection means, the phase of said AC output of said photodetector is compared with a phase of a reference signal by a phase comparison means, and said driving speed is controlled by both the outputs of said voltage difference detection means and said phase comparison means.
