Abstract

The contrast and resolution of contemporary ferroelectric liquid crystal (FLC) optically addressed spatial light modulators (OASLM) were measured in time-average and instantaneous modes while the devices were cycled at multikilohertz rates. The inherent, full cycle, write/read/erase response time was 270 μs. The time-average contrast peaked at 54:1 at 3.5 kHz when a 9 lp/mm resolution was used for evaluation. Instantaneous resolutions of 57 and 32 p/mm were obtained when the FLC-OASLM was operated at repetition rates of 900 and 2700 Hz, respectively.
