Paper Abstract

Time-interval statistics of the trigger impulses, corresponding to photo-electron impulses of certain rate are studied for laser anemometry use. Expressions are given for the frequency distribution of time intervals between trigger impulses. The distribution function of the channel content as probability variable is determined. The results of numerical calculations are presented for the case of two models of illumination patterns of the sample. It is proved in both cases that on the frequency distribution curve there occurs maxima corresponding to the particle velocity. By using the image of a diffraction grating proposed here, the present signal processing can directly measure the velocity distribution of particles with higher precision. The full statistical description presented provides the possibility of the comparison with other signal processing methods.
