ABSTRACT:
An optical guide for horizontally aligning two vertically stacked images generated by one or two SLMs. The optical guide has a channel separator that directs both images along two different paths. A pair of aligning reflectors on each path vertically shift the images with respect to each other so that at least part of the images on the first path are aligned side-by-side with at least part of the images on the second path. The channel separator then redirects the images to the image plane. Along both paths, at least two of the reflecting surfaces of channel separator or aligning reflectors are optically powered so as to change the width or height of the images.
