Abstract
An optical guide for horizontally aligning two vertically stacked images generated by one or two SLMs. The optical guide has a beam splitter that directs both images along two different paths. A first and a second aligning reflectors each disposed along each path for aligning the images. The beam splitter then redirects the images to the image plane 15. Along both paths, at least the aligning reflectors are optically powered so as to change the width or height of the images.
