Area of Expertise

Dynamic interferometry, new company start-ups


James C. Wyant received the B.S. in physics in 1965 from Case Western Reserve University and M.S. and Ph.D. in optics from the University of Rochester in 1967 and 1968. He was an optical engineer with the Itek Corporation from 1968 to 1974, when he joined the faculty of the Optical Sciences Center at the University of Arizona, where he now is a Professor of Optical Sciences and Dean of the College of Optical Sciences. He was a co-founder of the WYKO Corporation, 4D Technology, and DMetrix and the president of WYKO from 1984 to 1997. Wyant was a member of the Board of Directors and Executive Committee of OSA, the Optical Society of America, and he was the 1986 president of SPIE, the International Optical Engineering Society. Wyant has received several awards including the OSA Joseph Fraunhofer Award in 1992 and the SPIE Gold Medal in 2003.

Lecture Title(s)

Dynamic Interferometry
The largest limitation of phase-shifting interferometry for optical testing is the sensitivity to the environment, both vibration and air turbulence. In many situations the measurement accuracy is limited by the environment and sometimes the environment is sufficiently bad that the measurement cannot be performed. Recently there have been several advances in dynamic interferometry techniques for reducing effects of vibration. This talk will describe and compare dynamic interferometry techniques.

Advances in Interferometric Surface Measurement
The addition of electronics, computers, and software to interferometry has provided tremendous improvements in the measurement of surface shape and roughness. This talk will describe three such improvements; use of computer-generated holograms for testing aspheric surfaces, techniques for performing interferometric measurements more accurate than the reference surface, and two single-shot phase-shifting interferometric techniques for reducing the sensitivity of an optical test to vibration and measuring dynamically changing surface shapes.

Experiences Starting and Growing Optics Companies
Prof. Wyant has been involved in the starting and running of three optics companies: WYKO Corporation (1982 - 1997), 4D Technology (2002 - Present), and DMetrix (2001 - Present). This talk covers his experiences with these companies and the advice he would give to others who want to experience the joy, excitement, and hard work of starting and growing a company.
