Zusammenfassung:Methods of calibrating and operating optical switches as well as optical switches in which the orientations of mirrors are measured and controlled using control light beams and position sensing detectors are described. The present invention may provide high resolution control of a plurality of mirrors in an optical switch and this allow the optical switch to cross-connect a large number of input and output ports with a low insertion loss.
