Abstract: This disclosure relates to various implementations improve operational lifetime for a spatial light modulator device. One or more controllers are able to determine a target duty cycle based on an operating condition for a spatial light modulator device. The spatial light modulator device comprises one or more light modulation components that modulate light. The controllers allocate a refresh time period for encoding spatial light modulator refresh instructions based on the target duty cycle and encode spatial light modulator refresh instructions within the refresh time period. Afterwards, the controllers transmit the spatial light modulator refresh instruction to the spatial light modulator device.

Abstract: The pupil formed by an optical apparatus is expanded by use of a beam splitter to replicate the pupil and a waveguide to further replicate the replicated pupil. An optional rotator element can rotate a portion of the light split by the beam splitter to provide consistent polarization of light in the optical apparatus. In some embodiments, the beam splitter replication expands the pupil in one direction, while the waveguide replication expands the pupil in a second direction.
