Scientists have developed a high-efficiency beam steering angle expander consisting of two liquid crystal polymeric diffractive optical elements. For a LiDAR (light detection and ranging) operating at 905 nm, the steering angle can be expanded by 5.4 times. Potential applications include autonomous vehicles and eye-tracking for virtual reality displays.
