Large stepwise non-continuous beam steering with a few-hundreds microseconds response time liquid crystal technology based on combination of polarization grating and grating diffraction

Stepwise (non-continuous) large beam steering angle with fast response speed based on specific liquid crystal technology with a simple liquid crystal panel configuration is discussed. This technology enables over +/- 10 degrees stepwise beam steering with less than 300 microseconds response time at room temperature. This technology is endorsed by some combination effect between polarization grating and diffraction grating in conjunction with applied voltage dependent switching direction liquid crystal technology known as an SSD-LC (Smectic Single Domain Liquid Crystal) technology.
