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.
