Abstract

The possibility of using strongly focused coherent Gaussian beams diffraction for cardiovibration measurements is considered on the basis of a numerical modeling conducted for this type of light scattering from the vibrating rough surface. The optical scheme for cardiovibration measurements is suggested. The forming of output signal of the measuring system has been studied. The region of parameters when the considered system operates in linear regime has been determined. The influence of profile statistics on investigated system output characteristics has been analyzed.
