Abstract

An image-processing technique based on temporal coherence differences in a scene is described. Resultant processed images are presented that demonstrate an increase in the signal-to-clutter ratio of the order of 102 for a He–Ne laser in a white-light background (FWHM 200 nm). Problems of processing speed, dynamic range, and image misalignment are addressed. Modifications in both the optical design and electronic signal processing are proposed. Comparison with nonimaging experiments indicates that signal-to-clutter gains approaching 108 are feasible.
