  • Patent number: 11789331
    Abstract: A voltage-controlled optical wedge is formed by creating an adjustable voltage gradient along the length of a relatively large-sized LC cell. A pair of bias voltages (AC voltages) are applied at the opposing side terminations of the LC cell, their RMS values selected to create a continuous phase variation along the length of the cell, where a defined phase variation is associated with a specific beam steering angle. Adjustments in the applied bias voltages (specifically, changes in the RMS values of the bias voltages) result in changing the beam steering angle, providing for active, controllable beam steering as a function of time. The LC cell may be configured to provide either a linear or nonlinear continuous phase variation, as preferred for different beam steering applications.

  • Patent number: 11768419
    Abstract: A beam steering system may include a dynamically controllable liquid crystal (LC) beam steering device including an array of multiple LC beam steering segments, an upstream lens array arranged upstream of the beam steering device, and control electronics configured to control the beam steering device to output a directionally steered light. The upstream lens array includes multiple upstream lens elements, each configured to reduce a beam width of a respective light beam to provide a reduced-diameter light beam to a corresponding LC beam steering segment in the multi-segment LC beam steering device. Providing reduced-diameter light beams to the beam steering device may reduce unwanted beam steering effects and provide an improved beam steering efficiency of the beam steering system.
