29 December 1993 Stroboscopic interferometry of high-speed scanning mirrors

Advances in lasers, solid state detectors, electronics, and computational and display capabilities have made a reality of filmless recording, precision dynamic testing, and real-time processing of optical interference fringe patterns. Stroboscopically produced fringe patterns of the mirror-facet surface of a cylindrically shaped and a conically shaped scanner heat for `monogonal' scanners correlate with the predicted dynamic deformations from finite element analysis (FEA) at rotational speeds of 10 krpm and 20 krpm.
