Holography Pioneer Passes Away 54
Hal-9001 writes "The New York Times has an article on Emmett Leith, professor of electrical engineering at the University of Michigan and inventor of three-dimensional holography, who passed away on Dec. 23, 2005. Professor Leith and his coworker Juris Upatnieks displayed the world's first three-dimensional hologram at a conference of the Optical Society of America in 1964."

I think that statement would have given Prof. Leith a good laugh. He had a cartoon on his office door illustrating the difference between classical and quantum barriers. In the classical case, this guy is making faces at a lion on the other side of the barrier because the lion cannot penetrate the barrier. In the quantum case, the guy is running for his life because the lion has tunneled through the barrier...

No, as the article says, Dennis Gabor invented holography and coined the term "hologram", in 1948.
Leith created the first laser holograph, which was a big deal, and made holographs vastly more practical, and he deserves tons of credit for that, but not the same as inventing the field. There's a reason Gabor won a Nobel prize.

Leith created a hologram, not a hologrpah.
holograph - A document written wholly in the handwriting of the person whose signature it bears.

gabor is credited as being the one of the first to invent holography, leith for having innovated the use of a laser and later the off-axis technique.
not making this distinction is like creditiing henry ford for the invention of the automobile.

Actually the off-axis technique came before laser holography, and the off-axis technique really is a big deal--a Nobel-Prize-worthy big deal--since the twin-image problem caused holography research to stagnate for years. By 1955, even Gabor had pretty much given up on holography because of the twin-image problem. After Leith and Upatnieks solved the twin-im

My original statement is correct because of the words I have emphasized in bold face. Gabor only made holograms of two-dimensional objects (specifically of a transparency of the words "Hugyens", "Young", and "Fresnel" and of a transparent protractor). Admittedly part of the reason for this was because of the lack of a light

The Museum of Holography [holographiccenter.com] is an awesome visit if you come to Chicago for any reason. It is minutes outside of downtown and half hour from O'hare. It is really an interesting place (a bit commercialized lately) and the greatest thing is it completely passed the Wife Acceptance Factor as Oprah's HARPO studios is just down the street. Drop the lady off at their store and hit the Museum of Holography.

It came with a bunch of optics, a laser, sandbox, film, etc. I wonder if Bill Gates was bored one weekend and started shooting the laser at some of his Windows XP cd-roms?! Those CD's are incredible, they are one big hologram!

Besides Leith and others, it mentions Dennis Gabor, who originally developed the theory behind it all, in 1947.
