[2007] Optical alignment with computer-generated holograms

Burge, James H., Rene Zehnder, and Chunyu Zhao. “Optical alignment with computer-generated holograms.” Optical System Alignment and Tolerancing. Vol. 6676. SPIE, 2007.


Computer generated holograms (CGHs) have been successfully used for wavefront correction for measuring aspheric surfaces. Features on the CGHs have assisted the alignment of the optical test equipment. CGHs can also be used to provide alignment references for other complex optical systems. This paper discusses the types of CGHs that can be used for optical alignment and gives some examples.
