Abstract
The application of laser speckle and speckle-interferometric methods to cardiovibrations measurements is presented. The homodyne and heterodyne measuring techniques that use the Michelson mterferometer are compared. As shown, the space-time projections of the mterferometer output signal can be useftil for analysis of biovibrations. New diffraction methods based on speckles dynamics with a small number of scatterers are suggested that allow pulse waves to be sensed and recorded without distortion. Keywords: speckles, interferometiy, cardiovibrations, pulse waves
