Dynamic speckle interferometry of the microscopic processes

Abstract

Ratio between a time spectrum of differences of phases of the scattered waves and a time spectrum of speckle brightness is theoretically established. Three experiments in which the difference of phases of waves changed by moving of a rough glass plate, by fatigue of metal, and by the activity of a monolayer of cells are considered. The good agreement of the theory and experiment is received. © 2012 Copyright SPIE.
