Paul Yoder (BS Physics, Juniata College, 1947; MS Physics, Pennsylvania State University, 1950) began his career in optical engineering in 1948 under the guidance of Prof. David Rank in the Spectroscopy Laboratory at Penn State. He was employed for 10 years in the Optical Design Department of the U.S. Army’s Frankford Arsenal and then worked for 25 years on a variety of aerospace optical systems programs at Perkin-Elmer Corp. Following retirement in 1986, he was an optical engineering consultant, largely in the development of excimer laser recontouring of the human cornea for vision correction. He is a Fellow of SPIE and the OSA, has taught many short courses in optomechanical engineering for SPIE, and authored several books on optomechanics.
Daniel Vukobratovich is currently a Senior Principal Multi-Disciplinary Engineer at Raytheon Systems in Tucson, Arizona. Prior to Raytheon, he worked for fifteen years at the Optical Sciences Center, University of Arizona, where he still holds an adjunct faculty position. His primary field of interest is optomechanical design. He has authored over 50 papers, including chapters on optomechanics in standard reference works such as the IR Handbook and CRC Handbook of Optomechanics. He has taught optomechanics in 12 different countries, consulted for over 40 different companies, and holds several patents. He is a member and Fellow of SPIE, and he has received an IR-100 for work on metal matrix composite optical materials.
