Two-Dimensional Digital Beam Steering Based on Liquid Crystal Phase Gratings

Two-Dimensional Digital Beam Steering Based on Liquid Crystal Phase Gratings

Electrically tunable phase gratings are able to steer an incoming light beam without employing movable parts. Here, we present the design and implementation of a 2D beam steering device by cascading two orthogonal 1D liquid crystal (LC) based phase gratings, each having an array of 72 rectangular in...
