发明名称 Single element optics for passive facet tracking
摘要 A double bounce passive facet tracking system uses a single passive optical component of a toroidal mirror to induce a beam of light to track a facet of a dual mirror rotating polygon. A beam focused in both the tangential and sagittal planes is reflected from a convex facet of the polygon mirror to the toroidal mirror. The toroidal mirror collimates the light beam in a tangential plane and focuses the beam in the sagittal plane so that the beam is collimated in the tangential plane and focussed in the sagittal plane when it reaches the flat facet of the polygon mirror.
