Abstract
An internally reflecting rotating polygon system for correcting wobble by double reflection from the active facet without bow is disclosed. Instead of the impinging light source being transverse to the axis of rotation of a rotating polygon, this rotating polygon 52 having internally reflecting facets 54 at a draft angle to the axis of rotation, a collimated light source impinges upon a rotating polygon 52 with the facets 54 having the predetermined draft angle D. A., and angles of incidence at the first and second reflections. By two further reflections, 56, 58, the light is then reimpinged upon the same facet 54; wobble is similarly corrected, but with no effects of bow.
