Real-time computer-generated hologram by means of liquid-crystal television spatial light modulator

Opt Lett. 1986 Nov 1;11(11):748-50. doi: 10.1364/ol.11.000748.


A novel use of liquid-crystal television (LCTV) is described. It is shown that, if the phase nonuniformity of the LCTV is corrected by a liquid gate, then a simple computer-generated hologram can be written and coherently reconstructed.
