Abstract

The possibility is investigated of determining geometrical and dynamic parameters of the objects through space-and-time analysis of intensity distributions of their coherent images. When the objects are satisfactorily resolved by the imaging system, Fourier-Fresnel time transform of the intensity distribution of their coherent images determines the object shape and surface roughness parameters and the distributions of velocities and accelerations along the surface of an arbitrarily moving shape changing object. When the moving objects are not resolved, this transform enables obtaining autocorrelation function of coherent images which provides determination of the object shape.
