Paper Abstract

A ten-facet precision machined mirror with an air-bearing spinner was developed for use in laser-scanner and laser recorder systems. An interferometer, constructed to measure facet flatness, also revealed surface microstructure contributing to the mirror's noise figure. Pyramidal errors of the polygon were measured using a highly sensitive but simple optical, setup which enabled measurements to be taken in of static and dynamic modes.
