Tribute to James C. Wyant: The Extraordinaire in Optical Metrology and Optics Education.
High speed interferometry (HSI) is one of the enabling technologies to the successful development and testing of the James Webb Space Telescope (JWST) optical system that consists of a 6.5 meter diameter, segmented, lightweight primary mirror and lig

During the testing of the primary mirror segments for JWST, our team realized that some of the tools and techniques we had developed could be pushed further to achieve picometer resolution.We began developing incremental techniques for measuring, con

Future space observatory missions are forecasting the need for sensing and controlling wavefront error and system alignment stability to picometer scale. Picometer stability performance demands precision knowledge of the mirror and metering structure

Based on our results of the James Webb Space Telescope (JWST) center-of-curvature tests where we were able to measure dynamic amplitudes of Zernike terms to the order of a few picometers, we have applied the same approach to determine if it is possib

A high-speed interferometer has been designed and built to measure the dynamics of the James Webb Space Telescope primary mirror system currently under testing. This interferometer is capable of tracking large absolute motion (i.e., piston) of the mi
