LIDAR: MEMS OPTICAL PHASED ARRAY (OPA) FOR LIDAR

Optical beam steering device is a key enabling technology for light detection and ranging (LiDAR), free-space optical communication, and augmented reality/virtual reality. Most of the current beam scanners employ mechanical scanning units such as motors, which are bulky, slow and often unreliable. Solid-state beam scanners with integrated scanning elements have received increasing interests. In…
