Abstract: The disclosure herein describes reduction of undesired signals within reflected signals of a light detection and ranging (LiDAR) system. For example, a current injection circuit can inject an interference reduction current into an optical detector. Further, for example, an adjustable detection threshold may be adjusted during an undesired signal time period. Still further, for example, a switch can be used to disconnect various detection circuitry to avoid or mask undesired signals.

Abstract: An active metasurface that provides low-loss and high-bandwidth modulation control of light includes a number of cells arranged on a substrate. A controller dynamically alters a voltage differential supplied to the electrodes of each of the cells is adapted to alter refractive index of each of the high-index dielectric blocks in order to controllably steer light exiting the cell.

Abstract: Implementations described and claimed herein provide a mechanically-scanning 3-dimensional light detection and ranging (3D LiDAR) system including a galvo mirror attached to an armature of a galvanometer to reflect a light signal generated by a light generator, the galvanometer comprising at least one permanent magnet, at least one coil configured to carry current to move the armature, wherein the galvo mirror is configured to reflect the light signal generated by the light generator towards a one or more objects and the galvo mirror is further configured to reflect light signal reflected from the one or more objects towards a light detector.
