Abstract:
1. An illumination system for spatially multiplexing and synthesizing multiple laser beam sources, comprising: illumination optics aligned on a projection axis that is orthogonal to an offset axis; a first laser in a first plane orthogonal to the projection axis; first folding optics positioned in the first plane to fold a first beam from the first laser to a first portion of the illumination optics comprising a first segment of a stacked collimating lens; a second laser in a second plane parallel to, and offset along the offset axis from, the first plane; second folding optics positioned in the second plane to fold a second beam from the second laser to a second portion of the illumination optics comprising a second segment of the stacked collimating lens, wherein illumination optics synthesizes the first and second beam by spatial multiplexing.
