Abstract

A calculation of the autocorrelation function of a signal from a laser homodyne spectrometer generated by laminar flow of a liquid with a velocity gradient in the case of probing inhomogeneous laser beam is reported. It is shown that under certain conditions the time correlation scale of the spectrometer signal represents the velocity gradient and is independent of the coherence radiation. The results are given of a numerical modeling of the spectrometer signal energy spectra.
