Abstract

A novel laser beam deflector that utilizes rotating holographic gratings in a pyramidal geometry is described. Total rotational symmetry with regard to imaging properties is achieved with this deflector geometry, and therefore, it can be used for either flat-field or internal drum scanning applications. The scan beam from this deflector is bow free and totally uneffected by deflector wobble and centration errors.
