24‐3: Distinguished Student Paper: Towards a Solid‐State LIDAR Using Holographic Illumination and a SPAD‐Based Time‐Of‐Flight Image Sensor

Abstract

Light Detection and Ranging (LIDAR) systems are finding their way into an increasing number of applications including autonomous vehicles. Imaging based on Single Photon Avalanche Diode (SPAD) arrays has demonstrated great promise for LIDAR, typically using flood illumination or raster‐scanning of a small spot. Holographic illumination, on the other hand, has been successfully applied to display systems such as automotive Head Up Displays (HUDs). It holds promise as the method of illumination for a LIDAR system. We present a novel architecture and report initial results to show that it can improve the depth accuracy of 3D imaging.
