Abstract
A coherent optics technique of obtaining heart beats time series is presented. The method uses a dependence of properties of speckle-structures formed by focused coherent light field diffraction from a rough surface on the surface statistics and movement parameters. Computer simulation was applied to analyze different components of skin surface vibration and their influence on speckles dynamics was investigated.
