Abstract

An analytical relationship between the contrast in polychromatic image speckle patterns and the positions of the diffuse object's surface normal, the illumination, and the axis of the imaging system has been obtained. When the axis coincides with the direction in which the mirror reflects the illumination about the normal, the contrast in the image speckle pattern is the greatest. Some qualitative experimental results are also given.
