Abstract

The coherence control of object illumination is of particular interest for the improvement of the image quality of a small-scale object. In the past, however, it was almost impossible to get at a practically available, strong, coherence-controllable illumination source. In this context[1,2] acousto-optic coherence modification using a laser beam has been examined to yield a spatially coherence-controllable illumination. The intent of this paper is to present its principle and to see how the image reshaping of an edge object is made, depending on the illumination condition of spatial coherence.
