Abstract
An optical system has projector optics aligned on a projection axis that is orthogonal to an offset axis. A first laser is positioned in a first plane orthogonal to the projection axis. First folding optics are positioned in the first plane to fold a first beam from the first laser to a first portion of the projector optics. A second laser is in a second plane parallel to, and offset along the offset axis from, the first plane. Second folding optics is positioned in the second plane to fold a second beam from the second laser to a second portion of the projector optics to synthesize the first and second beam.
