摘要：
This paper presents the results of a study of the accuracy of the most promising laser Doppler velocity meters with splitting of the laser beam amplitude and a Gaussian distribution of the light intensity in the beams. It is assumed that the electronic signal processing system is constructed on the ″frequency-code″ or ″frequency-analog″ conversion principle and yields the average velocity value after a rather long time interval and the ″instantaneous″ value in the form of analog signal or codes in a short time interval. The systematic error of the LDVM, caused only by the random nature of the appearance of particles in the focal region of the instrument, is investigated.
