Lidar System with Nonmechanical Electrowetting-Based Wide-Angle Beam Steering

Abstract

A light detection and ranging (lidar) system with +/- 90 deg of steering based on an adaptive electrowetting-based prism for nonmechanical beam steering has been demonstrated. Electrowetting-based prisms provide a transmissive, low power, and compact alternative to conventional adaptive optics as a nonmechanical beam scanner. The electrowetting prism has a steering range of +/- 7.8 deg. We demonstrate a method to amplify the scan angle to +/- 90 deg and perform a one-dimensional scan in a lidar system.
