Beschreibung
Zusammenfassung:	A switched pixel array LiDAR includes a transmit optical switching network and a receive optical switching network. The transmit optical switching network is connected to a transmit antenna in each pixel of the switched pixel array, and a receive optical switching network is coupled to receive antennas in each pixel. The transmit antenna length is at least 100 times greater than the transmit antenna width. The transmit optical switching network steers a transmit beam from a laser system to the transmit antenna in a selected pixel, and emits the transmit beam through a cylindrical lens towards a target. The transmit beam is reflected off the target as a receive beam passing through the cylindrical lens towards the receive antennas in the selected pixel. The receive optical switching network transmits the receive beam to an optical receiver system which generates a receive signal configured for extraction of sensor data associated with the target.
