This paper presents the results of studies of a photoelectric autocollimator with a detector based on a linear CCD array and a computer as a spectrum analyzer. The threshold sensitivity of the device to the image displacement depends on the SNR. When the SNR equals 250, the threshold sensitivity is 0.134μm, which corresponds to a threshold sensitivity to rotation of the test mirror by no more than 0.007. The device makes it possible to determine the power spectrum of the rotational-velocity fluctuations of rotating mirrors, as well as the spectrum of the radiation fluctuations of distant sources.
