Juris upatnieks biography definition

Holography is a technique which enables three-dimensional images to be made. It involves the use of a laser, interference, diffraction, light intensity recording and suitable illumination of the recording.

The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object were still present, thus making the image appear three-dimensional.

The holographic recording itself is not an image; it consists of an apparently random structure of either varying intensity, density or profile.

The development of the laser enabled the first practical optical holograms that recorded 3D objects to be made in by Yuri Denisyuk in the Soviet Union[5] and by Emmett Leith and Juris Upatnieks at the University of Michigan, USA.[6] Early holograms used silver halide photographic emulsions as the recording medium. They were not very efficient as the grating produced absorbed much of the incident light.

Various methods of converting the variation in transmission to a variation in refractive index (known as "bleaching") were developed which enabled much more efficient holograms to be produced.

Emmett Leith (March 12, in Detroit, Michigan – December 23, in Ann Arbor, Michigan) was a professor of electrical engineering at the University of Michigan and, with Juris Upatnieks of the University of Michigan, the co-inventor of three-dimensional holography.

Leith received his B.S.

in physics from Wayne State University in and his M.S. in physics in He received his Ph.D.
