Abstract

The dynamic behaviours of laser speckles caused by a uniform in-plane movement of a diffuse object are investigated by deriving the general formulas of the intensity cross-correlation function in both the diffraction and image fields of the object. The formulas obtained suggest the new methods of pattern correlation and MTF measurement. Validity and applicability of these methods are verified experimentally.
