Abstract
Example embodiments relate to using cleaning protocols to monitor defects associated with light detection and ranging (lidar) devices. An example embodiment includes a method. The method includes applying, using a cleaning device, a cleaning protocol to one or more optical components of a light detection and ranging (lidar) device. The method also includes emitting, from a light emitter of the lidar device, one or more light signals. Additionally, the method includes detecting, by a light detector of the lidar device, reflections of the one or more light signals. Further, the method includes determining, by a controller of the lidar device based on the detected reflections of the one or more light signals, that one or more defects are present within the one or more optical components or within the cleaning device.
