One beam of intense monochromatic light hits the subject, then is refracted onto a photographic film.  A second beam goes directly to the film, setting up an interference pattern. The resulting process has  been used in everything from movies to seismic exploration to advertising to micrography, and
One beam of intense monochromatic light hits the subject, then is refracted onto a photographic film.  A second beam goes directly to the film, setting up an interference pattern. The resulting process has  been used in everything from movies to seismic exploration to advertising to micrography, and led to a  1971 Nobel Prize for its creator. FTP, name this system of three-dimensional imaging invented by Dennis  Gabor.
