A method of detecting optical subsystem failures includes emitting a pulsed light beam (120) from a laser (102) through a window (122). A reflection signal (150a, 150b, 150c) indicative of a portion of the beam reflected by the window is compared to an expected signal to monitor for degradation of an optical component (104, 106, 110, 112, 114, 122). |
