Abstract

The motion of speckles produced by a rotating diffuse object with a spatial velocity distribution was investigated. It was shown that speckle motion in a two-lens imaging system depends on the Doppler-shift frequency distribution that is due to the spatial velocity distribution of the diffuse object within the point spread of the optical system used. By measuring the time correlation of speckle intensity fluctuations, the predicted properties of the speckle motion that exhibit a good agreement with the experimental results are presented.
