A method to assess steadiness of movable mirror of Michelson interferometer in Fourier’s spectrometer has been developed. Steadiness of movable mirror motion has been analyzed experimentally using three devices with different control systems of the movable mirror. A comparative analysis of the speed steadiness of the frame motion has been made, using analog and digital control types, with and without feedback. We have found that the developed method helps to analyze the above mentioned process faster if there is an interference pattern. We have shown that the control system without feedback has more deviation of speed motion than one with feedback.
