Alignment and verification of optical systems using computer generated holograms
On demand | Presented live 19 June 2024 
Abstract
The precision of interferometry combined with the ability of computer generated holograms to accurately create arbitrary wavefronts provides the gold standard for measuring aspherical optical components. The additional ability of a single CGH to simultaneously create multiple perfectly aligned wavefronts opens the door for more complex metrology for aligning and verifying optical systems. This talk summarizes the general capabilities of CGH metrology and provides some examples where simultaneous measurements of multiple optical elements are used for efficiently aligning and accurately verifying optical systems.

Daewook Kim is an associate professor of Optical Sciences and Astronomy at the University of Arizona. He has devoted his efforts to a multitude of space and ground-based large optical engineering projects. His primary research focuses on precision freeform optics design, fabrication, and various metrology topics, including interferometry and dynamic deflectometry. His contributions cover a broad spectrum of wavelengths, ranging from radio to x-ray. Kim has played various roles in numerous astronomical optical engineering projects. Notable among these are his involvement in designing and assembling the NASA Aspera UV space telescope, conducting the fabrication and testing of the 25-meter diameter Giant Magellan Telescope primary mirror segments, designing the South Pole Telescope’s SLIM instrument for wide-field-of-view radio signal detection, and spearheading the development of technology for thermoforming antenna panels for the next generation of very large array radio telescopes, amo
