The
principle was discovered
by Dennis GABOR in 1947 (N0BEL Prize
in 1971) but it was necessary to wait for the updating of laser technology
to see his application
at the beginning of the sixties at the same time in the U.S.A. and in
Russia.
Of
note, are the american physicians LEITH et UPATNIEKS who applied the
laser technology to the GABOR's invention, the russian Yuri DENISYUK
was inspired by the Gabriel LIPPMAN's work, the French physician who
invented a color photography produced by Bragg diffraction. (N0BEL Prize
in 1908).
