摘要

In the paper on the base of theoretical and experimental analysis it is shown that the spectrum of intensity fluctuations contains the high frequency peak in the absence of subsidiary reference wave at non-small angles of speckles observation. Such phenomenon, interpreted as new type of manifestation of Doppler effect, is habitual only for the case of strongly focused coherent beam scattering. In the paper the possibilities of the usage of observed effect in the measurements of blood flows in narrow capillaries are discussed. Traditional Doppler method utilizing the strongly focused Gaussian beam scattering is considered. It is shown that the frequency position of Doppler peak in the spectrum of intensity fluctuations of measurements is defined not only by The angle of speckles observation but also by the relation between the waist beam diameter and the average size of flow inhomogeneities. Such result was experimentally verified.
