Abstract
A system for ensuring the integrity of the enclosure of a wireless power transmitter. The enclosure of the transmitter comprises a window in order to allow a high-power beam to exit the transmitter. The window is equipped with an area which reflects at least a portion of the beam, and directs the reflected beam onto a detector. Thus the system can ascertain whether the window is undamaged, since if the detector is receiving a satisfactory portion of the beam, then it is indicative of an undamaged window. This advantageously prevents dangerous beam generated damage which may be caused if the exit window of the transmitter is damaged. The laser beam is preferably circularly polarized before exiting the transmitter to prevent dangerous laser damage caused by the reflections of the maximum of the P or S polarization components, which may occur with linearly polarized beams.
