Abstract

Demonstration of coherence modulation of light is reported for the first time in the area of acousto-optic signal processing. The method allows electro-optic modulation of broadband sources to be used in acousto-optic time integrating correlators, with a modulation depth and a dynamic range comparable to those of coherent systems. Though a single coherence-modulated channel is used, it demonstrates that a generalization of the method to several channels is possible.
