Light Detection and Ranging (Lidar) Devices Having Vertical-Cavity Surface-Emitting Laser (VCSEL) Emitters
Abstract:
Example embodiments relate to light detection and ranging (lidar) devices having vertical-cavity surface-emitting laser (VCSEL) emitters. An example lidar device includes an array of individually addressable VCSELs configured to emit light pulses into an environment surrounding the lidar device. The lidar device also includes a firing circuit configured to selectively fire the individually addressable VCSELs in the array. In addition, the lidar device includes a controller configured to control the firing circuit using a control signal. Further, the lidar device includes a plurality of detectors. Each detector in the plurality of detectors is configured to detect reflections of light pulses that are emitted by one or more individually addressable VCSELs in the array and reflected by one or more objects in the environment surrounding the lidar device.
