Abstract

This paper describes an optical processor capable of forming real-time visible images of the radio sky directly from the output signals of a low-frequency T-type antenna array. Current modulator and light-valve technology could accommodate an array with 50-element crossbar and 25-element stem. Experimental confirmation of the correlator principle is described.
