Obtaining of sрасе-time projections of human cardiovibrations by speckle-interferometry
In this paper the investigations of the dependence of the space—time projection structure of speckle—interferometer output signal on heart disease seriousness have been carried out. The novel technique of heart disease diagnostics is suggested. The results of experimental investigations of pulse waves in norm, using the differential speckle—interferometer are described. The method, basing on focused coherent field diffraction and methods, utilizing the traditional speckle—interferometer Michelson type and differential speckle—interferometer for cardiovibration measurement are compared.
