Abstract
A time-integrating optical correlator has been devised in which a digital shift register-LED array combination provides the delay-and-multiply operation usually performed by an acousto-optic cell. The optical subsystem is extremely compact and should be able to operate at bandwidths from D. C. to 100MHz. Delay time range and resolution can be varied over a wide range simply by changing the frequency of the clock driving the shift register.
