LiDAR is a technique used for measuring distances with laser light. Researchers now show a new way to speedup a type of LiDAR engine by using photonic circuits. Light detection and ranging (LiDAR) comprised an array of techniques using laser light to measure distances by multiplying the time delay between transmitted and received optical signals with the speed of light. Modern 3D LiDAR sensors combine high lateral/vertical and radial resolution, and are key components in the ongoing revolution of level 4 and 5 self-driving cars.

The prominence of 3D LiDAR...
