Anyone who drives a vehicle knows about the device police use to keep the ‘speed demons’ in check. A Light Detection and Ranging (LIDAR) system uses a 130 μW 904 nm beam produced by three light emitting diodes (LEDs), and a telescope working together in order to calculate how long it takes for the beam to leave the device and return to the telescope. This application note describes how to use Ophir products to test LIDAR guns for performance by assessing the power output of the beam, and testing the three LEDs that produce the beam.
