A simple electronic correlator for two-time photoelectric correlation measurements has been developed. It functions by registering the distribution of time intervals between pairs of photoelectric pulses. Its basic elements are a clock that is started by the first pulse and is used to digitize the time intervals, a pair of fast counters for counting subsequent pulses, and a set of data registers. The pulses are directed to one or the other counter alternately at regular clock intervals. The operation of the correlator is described and tested by measurements of a randomly modulated light source.
