Abstract: In certain embodiments, a system for sensing occlusions in an optical system includes a first laser source configured to generate optical signals and a set of optical elements arranged to receive the optical signals from the first laser source and to direct the optical signals along a beam path. The system also includes a detector arranged to receive reflections of the optical signals traveling along at least a portion of the beam path and a control system communicably coupled to the detector. The control system is configured to detect, based on signals generated by the detector, reflection signals associated with the reflections of the optical signals, and disable a second laser source based on detection of the reflection signals.
