Abstract

The inputs to optical correlators have in general always been an amplitude modulated input either in a binary or in an analog fashion. Little work has been done on the performance of phase modulated inputs to optical correlators. Simulations are performed using phase inputs and amplitude inputs binary and analog and the Homer efficiency is used as the metric of comparison. An ideal phase filter and classical matched filter cases were compared. Results show phase inputs are a viable means of encoding input information. 1 .
