ÜBERWACHUNGSSYSTEM DER DEGRADATION UND DER VERSCHMUTZUNG EINES SPIEGELS

摘要

The invention relates to a mirror monitoring system (100) comprising an analysis head (200) comprising a transmission head (204) adapted to emit a light beam towards the mirror, and a reception head Apparatus (206) adapted to receive a light beam from the mirror, wherein the receiver head (202) comprises a photodetector (230), an image sensor (228), and a partially reflective and partially transparent plate (232) arranged to separate the beam received by the receiving head into a first beam transmitted to the image sensor (228) and a second beam transmitted to the photodetector (230).
