摘要: High-birefringence liquid crystal (LC) in ultrathin LCOS panels was adopted to prepare high phase precision (mSTD =lambda/50) and phase accuracy (mAPAE%similar to 8%) with suppressed pixel-level crosstalk effects. In conjunction with optimized digital driving scheme, the zero order light loss was found directly related to the phase accuracy error. Meanwhile, the world's fastest pure phase modulation LCOS with a response time of similar to 0.87 ms at 45 degrees C was also achieved. The low-temporal flicker (P-P similar to 2.0%) with high-speed LC responses was demonstrated by applying new digital driving scheme. Finally, the 4K2 K LCOS-SLM (similar to 7000 PPI) was evaluated its difficulties and opportunities. (C) 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
