We describe a time-integrating acousto-optic correlator that allows se
veral channels to be multiplexed optically by means of a coherence-mul
tiplexed superluminescent laser diode. Parallel channels are generated
by birefringent electro-optic modulators set in cascade to induce opt
ical 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.
