Paper Abstract

A fully complex filter is discussed using a Boulder Nonlinear Systems Smectic A* liquid crystal spatial light modulator. Each pixel is capable of both analogue amplitude modulation and binary phase modulation. Two pixels are used together in a macro pixel giving full complex modulation.
