Illumination coherence effects in laser-speckle imaging: modeling and experimental demonstration

Abstract

Coherent imaging techniques rely on the coherence properties of backscattered radiation to form an image of an illuminated object. These techniques are sensitive to the degree of coherence of the illuminating source. We present an approach for simulating the effects that partial temporal coherent illumination has on these techniques. Computer simulation and laboratory experimental results are presented that illustrate illumination coherence effects on imagery obtained with the technique known as imaging correlography.
