Abstract
A system includes a driving apparatus configured to operate on an optically addressed spatial light modulator (OASLM) including a modulation layer notionally divided into a plurality of separately addressable segments. A pulse generator is configured to provide one or more voltage patterns and an optical pattern generator configured to provide one or more optical patterns of light. For each segment of the OASLM, the driving apparatus is further configured to write, over a predetermined number of write operations, a predetermined amount of light associated with the one or more optical patterns. The driving apparatus is configured to apply a reset pulse associated with the one or more voltage patterns, such that a resulting net charge on the modulation layer is zero.
