Light detection and ranging (LiDAR) systems have become the preferred method for enabling an automobile, an automated guided vehicle (AGV),
or even a robotic vacuum to “see” its surroundings. Drones and higher-flying aircraft also use LiDAR to navigate and map terrain at greater distances.
Though LiDAR has been well studied, designers must exercise great care when selecting key components such as the gate driver, the gate-switch FET, and
the laser diode necessary to create the optical pulses. This article provides an overview of LiDAR. It then presents examples of the critical
electro-optical components and shows how they work together to generate the necessary pulses.
