Continuous-wave light detection and ranging (LiDAR) using image-reject homodyne detection and PRBS modulation

Abstract

We present a continuous wave Light Detection And Ranging (LiDAR) sensor that instantaneously measures distance and radial velocity with strong immunity to interference (e.g., other LiDAR sensors, glare). By au-tomatically prioritising measured information based on velocity and range, our aim is to reduce the processing time required to execute safety-critical decisions in autonomous applications.
