Abstract

A spatial light modulator system includes an optically addressable spatial light modulator (OASLM) and an electrical addressable spatial light modulator (EASLM) arranged to transmit light onto the OASLM. A first controller is configured to address the EASLM with both a positive image and a negative image. A second controller is configured to apply a first bipolar voltage pulse to the OASLM associated with reception of the positive image and apply a second bipolar voltage pulse to the OASLM associated with reception of the negative image.
