Abstract

Up to now, several methods for velocity measurement using speckle dynamics have been proposed. They are based on the varlation of the correlation function or the power spectrum of speckle intensity. These methods are simple and rapid to apply to measure tangential component of body's velocity but accuracy of velocity measurement is rather low. The use of amplitude or phase grating to modulate the speckle pattern was suggested also for measurement of diffuse object velocity[1,2].
