55.2: Fast Switching Dual-Frequency Liquid Crystal Optical Retarder, Driven by an Amplitude and Frequency Modulated Voltage

We employed amplitude and frequency modulated voltage in fast switching optical retarder with a high pretilt angle dual‐frequency nematic cell. We obtained the response times 150 − 500 μs for an optical retardation shift on 0.3 − 2.2 μm in optical retarder with 12 μm thick nematic cell. The results...

Description
Summary:We employed amplitude and frequency modulated voltage in fast switching optical retarder with a high pretilt angle dual‐frequency nematic cell. We obtained the response times 150 − 500 μs for an optical retardation shift on 0.3 − 2.2 μm in optical retarder with 12 μm thick nematic cell. The results could be used in beam steering, adaptive optics and display devices.
