Computer Generated Complex Filter for an All Optical and a Digital Optical Hybrid Correlator

By Philip Birch, Rupert Young, Frederic Claret-Tournier, David Budgett and Christopher Chatwin


We present results of a correlation filter utilizing a computer-generated hologram using an analog ferroelectric liquid-crystal spatial light modulator (SLM). The SLM amplitude-modulates light and can induce a 0-p 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. © 2002 Society of Photo-Optical Instrumentation Engineers
