Paper Abstract

In connection with the parameters of the optical configuration used to produce speckles and under illumination of a gaussian beam over the diffuse object, this paper discusses the statistical properties of dynamic speckle produced in the diffraction and image fields by a moving diffuse object in a plane with constant velocity. Especially, the space-time correlation function of the dynamic speckle intensity is investigated in detail. Two typical speckle motions of translation and boiling are interpreted for various optical configurations in the diffraction and image fields. As one of the interesting applications of dynamic speckle to metrology, several methods for the velocity measurement of the diffuse object will be introduced.
