Juris Upatnieks (born 7 May 1936 inRiga) is aLatvian-American physicist and inventor, and pioneer in the field ofholography.
Upatnieks fled the Latvia with his parents at the close ofWorld War II, seekingasylum in Germany. In 1951 the family emigrated to the United States. He attended high school inAkron, Ohio, and studied electrical engineering at theUniversity of Akron, where he was awarded a bachelor's degree in 1960. Thereafter he studied at the Institute of Science and Technology of theUniversity of Michigan, where he earned a master's degree in electrical engineering in 1965. From 1973 to 1993 he worked at the Environmental Research Institute of Michigan and was an adjunct professor, Electrical and Computer Engineering Department at University of Michigan inAnn Arbor. There he taught a laboratory course in optics until 1996. From 1993 to 2001 he was a consultant with Applied Optics in Ann Arbor. From 1996 to 2001 he was also a researcher with the faculty of Mechanical Engineering and Applied Mechanics at the University of Michigan.
In 1964 he demonstrated, withEmmett Leith, the first three-dimensional holograms in the United States and together with Leith published a series of technical papers from 1962 to 1964.
As of 2009 Upatnieks holds 19 patents. Among them is a holographic gunsight.[1]
In 1975 he received theR. W. Wood Prize of theOptical Society of America and 1976 the Holley Medal of theAmerican Society of Mechanical Engineers. He was named "Inventor of the Year" in 1976 by the American Association for the Advancement of Invention and Innovation. He is a member of the Optical Society (Fellow) and ofInternational Society for Optical Engineering, as well as a member of theLatvian Academy of Sciences, whose Great Medal he received in 1999. In 2010, he received theEmmett N. Leith Medal.[2]
Upatnieks is holder or co-holder of twenty United States Patents in the fields of holography and coherent radiation.
