Abstract

Current rotating light beam deflectors (including polygon mirrors, optical disks, etc.) suffer performance/cost problems due to fabrication and assembly tolerance/- errors as well as errors due to dynamic deflections. In a typical system utilizing a multi-facet rotating polygon, each facet of the rotating polygon deflects the incident light beam from a stationary source such as a laser through a specific deflection angle onto an imaging/photoreceptor plane at which location a scan line is formed by each facet deflection. The spacing between each successive pair of scan lines should be as uniform as possible.
