First we depicted one theoretical model of LCoS device, and then working modes of LCoS used as phase-only SLM were selected and optimized by varied the twist angle of liquid crystals and polarized angle due to parameter space method, two working modes, which are suitable to apply LCoS as phase-only SLM, were found, that is (0°, 0°) and (0°, 52°). Theoretical study also showed that the (0°,52°) could be used as a compound device, it behaved property of intensity modulation if a working point was selected appropriately and it behaved property of phase modulation when another wording point was selected. At the same time, this two working modes were studied detailed by extended Jones matrix method.
