Paper Abstract

In the course of experimental examination of the blood circulation in the eye retina with use of laser Doppler anemometers (LDA) laser radiation is scattered both by the blood flow and optically inhomogeneous tissues. In this paper we consider the effect of the extra scattering on the LDA signal in terms of broken spatial coherence of the radiation in the retina. An explicit formula for the correlation function of the signal is obtained for a practical optical scheme that includes a crystalline lens, a pupil, and a concave retina as elements. The correlation function shows narrowing with spatial coherence of the radiation degrading. Most favorable configuration of the optics for the blood circulation intensity measurements and mapping in the retina are discussed.
