Patent ID: 8085452

Claim:
A holographic imaging system comprising: an electrically addressable spatial light modulator (EASLM); a write light configured to illuminate the EASLM; an optically addressable spatial light modulator (OASLM); a read light configured to illuminate the OASLM; and a controller configured to: address the EASLM with the write light in transmitting both positive and negative holographic sub-images to the OASLM, wherein the positive and negative holographic sub-images provide for a direct current (DC) balance of the EASLM; apply a blanking pulse to the OASLM in between transmitting the positive and negative holographic sub-images; and address the OASLM with an operating voltage, wherein the operating voltage is applied to different segments of the OASLM that the positive and negative holographic sub-images are written to, and wherein the OASLM is illuminated by the read light while applying the blanking pulse in generating a holographic image comprising the positive and negative holographic sub-images.
