Abstract

A multi-faceted photodeflector includes a plurality of groups of multiple mirrors circumferentially alternating about a rotation axis, each group consisting of the same number of mirrors. Each mirror of any particular one of the mirror groups is inclined, with respect to the rotation axis, at an angle different than the mirrors of all other mirror groups disposed about the rotation axis.
