Beam steering experiment with two cascaded ferroelectric liquid-crystal spatial light modulators
Original language description
The design, construction, and evaluation of a laser beam steerer that uses two binary ferroelectric liquid-crystal (FLC) spatial light modulators (SLMs) operated in conjunction are presented. The system is characterized by having few components and is inprinciple lossless. Experimentally, a throughput of similar to20% was achieved. The simple system design was achieved because of the high tilt angle FLC material used in the SLMs, which were specifically designed and manufactured for this study. By coherently imaging the first SLM onto the second SLM, pixel by pixel, we obtained an effective four-level phase structure with a phase step of 90degrees. An appropriate alignment procedure is presented. The beam steering performance of the system is reportedand analyzed
