High accuracy optical processors: a new performance comparison

A hybrid time and space integrating processor is shown to provide more than one operation per analog to digital conversion. A preferred performance measure, operations per second per component, is used to compare bit-sliced digital and high accuracy optical processors using the digital multiplicatio...

Description
Summary:A hybrid time and space integrating processor is shown to provide more than one operation per analog to digital conversion. A preferred performance measure, operations per second per component, is used to compare bit-sliced digital and high accuracy optical processors using the digital multiplication-by-analogconvolution algorithm. Optical system performance is shown to increase nearly quadratically with the speed of its components, while digital systems increase only linearly.
