Towards a solid‐state light detection and ranging system using holographic illumination and time‐of‐flight image sensing

Light detection and ranging (LIDAR) systems are finding their way into an increasing number of applications including autonomous vehicles. Image sensors based on single-photon avalanche diode (SPAD) arrays have demonstrated great promise for LIDAR, typically using flood illumination or raster-scanning a small spot. Holographic illumination, phase-only liquid crystal silicon (LCoS) spatial light modulators, has been successfully applied to display such as automotive head up displays (HUDs). It holds the method LIDAR system. We present novel solid-state architecture holographic projection detection. report simple experiment that demonstrates proof concept. The results show can improve depth accuracy 3D imaging compared conventional systems. also indicate several key performance advantages will increase system scales higher performance.
