HOLOGRAPHIC MOTION-PICTURE - THEORY AND OBSERVATIONS

We develop a full density-matrix theory describing the holographic mot ion picture, the direct recording of a real moving image into an inhom ogeneous spectrum of a medium using spectral hole burning. The main em phasis is on the time resolution of the movie. It is concluded that, w ith a frequency scan rate faster than the square inverse of the charac teristic time of the event, the moving image is faithfully recorded, t he only limiting factor being the bandwidth of the medium. From the nu merical simulation, the ultimate time resolution of the order of nanos econd is achieved when the scan rate is above 5 x 10(16) Hz/s for a cr yogenic Eu3+:Y2SiO5 crystal. An experimental demonstration of the movi e was performed for this crystal.
