The penomenon of coherent emission by a moving coarse surface subjected to disturbances in the form of transverse vibrations is theoretically and experimentally investigated. Spectral patterns of the output signal from a photodetector are obtained for a model of an object in the form of a rotating duralumin disk that completes small angular wobbles. The technique and its equipment realization help in detecting the transverse vibrations of moving objects that diffusely scatter light, particularly the angular wobbles of moving parts. The experimental results are in good agreement with theoretical representations.
