Profile Summary

My major research and development interests involve using old technology, interferometry, and new technology, computers and modern electronics, to produce "state of the art" instruments for solving metrology problems in many industries including data storage, semiconductor, machine tool, optical fabrication, fiber optics, printing, and biomedical.

I am interested in technical education, especially on the web or by computer.

Course Instructor
SC212: Modern Optical Testing
This course describes the basic interferometry techniques used in the evaluation of optical components and optical systems. It discusses interferogram interpretation, computer analysis, and phase-shifting interferometry, as well as various commonly used wavefront-measuring interferometers. The instructor describes specialized techniques such as testing windows and prisms in transmission, 90-degree prisms and corner cubes, measuring index inhomogeneity, and radius of curvature. Testing cylindrical and aspheric surfaces, determining the absolute shape of flats and spheres, and the use of infrared interferometers for testing ground surfaces are also discussed. The course also covers state-of-the-art direct phase measurement interferometers.
SC213: Introduction to Interferometric Optical Testing
This short course introduces the field of interferometric optical testing. Topics covered include basic interferometers for optical testing, and concepts of phase-shifting interferometry including error analysis. Long wavelength interferometry, testing of aspheric surfaces, measurement of surface microstructure, and the state-of-the-art of direct phase measurement interferometers are also discussed.
