Abstract
Motor-driven polygon mirror scanners are commonly used for beam deflection in laser printers, digital copy machines, bar code readers, laser micrometers, etc. The performance of scanners highly effects the positioning accuracy of laser beam and thus the performance of OA equipment. In practice, the stability of laser scanners is determined by the accuracy of polygon mirror and its drive. At present, in low profile, low cost compact scanners, a motor-driven polygon mirror scanner with built-in drive control circuit is used, and its stability is estimated by the dynamic characteristics measurement equipment.
