SC1041: Computer Generated Holograms for Optical Testing
This course provides the attendees with solid understanding of theory and useful practical skills for using computer generated holograms for optical testing. The class covers the following topics: • Computer Generated Holograms - underlying principles, types of CGHs and tradeoffs • Design of optical test systems that use CGHs for wavefront correction and alignment • Fabrication methods and limitations for CGHs • Error analysis for CGH testing • Methods of aligning and calibrating the optical test system
