Abstract
A method of monitoring distortion in a reflective surface of a spinning mirror, the method being constituted by (1) spinning the mirror; (2) directing a beam of radiation onto the reflective surface of the spinning mirror to generate a reflected beam; (3) positioning a radiation detector in the path of the reflected beam, whereby the radiation detector generates an electrical signal responsive to the shape of the reflected beam; and (4) monitoring the shape of the reflected beam by monitoring the electrical signal generated by the radiation detector.
