Abstract

We describe a time-integrating acousto-optic correlator that allows several channels to be multiplexed optically by means of a coherence-multiplexed superluminescent laser diode. Parallel channels are generated by birefringent electro-optic modulators set in cascade to induce optical path differences greater than the coherence length of the source. The system can be combined with most of the other previously reported multichannel techniques used in acousto-optic processors.
