Abstract
We present results of a correlation filter utilizing a computergenerated hologram using an analog ferroelectric liquid-crystal spatial light modulator (SLM). The SLM amplitude-modulates light and can induce a 0-? phase shift, which is equivalent to modulating along the real axis. Two pixels are combined into a macropixel using a phase-detour technique enabling full complex modulation. The method is used as the filter for a conventional optical correlator and in a digital-optical hybrid correlator.
