ILLUMINATION COHERENCE EFFECTS IN LASER-SPECKLE IMAGING - MODELING AND EXPERIMENTAL DEMONSTRATION

Coherent imaging techniques rely on the coherence properties of backsc attered radiation to form an image of an illuminated object. These tec hniques are sensitive to the degree of coherence of the illuminating s ource. We present an approach for simulating the effects that partial temporal coherent illumination has on these techniques. Computer simul ation and laboratory experimental results are presented that illustrat e illumination coherence effects on imagery obtained with the techniqu e known as imaging correlography.
