Snyder, Kwiatkowski Receive Kingslake Medal and Prize

01 October 2006
The 2005 Rudolf Kingslake Medal and Prize has been awarded to James J. Snyder and Stephen L. Kwiatkowski for their paper "Wavelength measurement with a Young's interferometer," published in the August 2005 issue of Optical Engineering. Selected by the Kingslake Award Committee, this paper is recognized for its innovative advancement of existing wavelength measurement technologies.
In the award-winning paper, the authors describe a fiber-optic laser wavelength meter based on a Young's interferometer. The wavelength meter described is similar to those based on Michelson and Fizeau interferometers, but simpler and more robust, thus making it ideal for field applications that require wavelength measurements from remote locations. In addition, the meter is more compact in size, requiring no reference laser, and is substantially faster than other wavelength meters. Based on their analysis, the authors conclude that with occasional recalibration, the wavelength meter is capable of accuracy better than one part in 105.

James J. Snyder
Snyder is a research professor with the Center for Precision Metrology, Department of Mechanical Engineering and Department of Physics and Optics, at the University of North Carolina at Charlotte. He founded/co-founded Blue Sky Research, Soquel Technology, and Fizeau Electro-Optic Systems, and holds more than two dozen patents. His current research interests include laser beam propagation codes, precision optical measurement, and laser wavelength meters.

Stephen L. Kwiatkowski
Kwiatkowski is at Lockheed Martin's Advanced Technology Center in Palo Alto, CA. His accomplishments include five patents and co-founding Soquel Technology. Kwiatkowski's research interests include guided-wave devices and their applications to metrology.
The Rudolf Kingslake Medal and Prize is presented annually in recognition of the most noteworthy original paper to appear during the previous year in the SPIE journal Optical Engineering, on the theoretical or experimental aspects of optical engineering. Award winners receive a citation and honorarium of $2,000.
