Paper Abstract

This paper concerns the realization of a noncoherent correlator: the positioning tolerances and light budgets of a noncoherent correlator, the effect of the wavelength spread of the noncoherent source, the need for multiplexing noncoherent filters, the best input device (CRT or SLM) to use in a noncoherent correlator, and the light budget for the different noncoherent correlators. We conclude that a laser diode with a diffuser and input SLM laser diode array is the best choice for light source and input device. We demonstrate that a laser diode array can also be used to multiplex CGH's and that this is the preferable architecture.
