An optical system has been developed for the compact storage and projection of conventional two-dimensional movies. Each frame of a conventional movie is stored holographically on a small area of a photographic plate or film. Successive frames are holographically recorded adjacent to each other on the film. The movie is replayed by scanning a reconstruction beam across the storage hologram and viewing the real image on a diffusing screen. All images are in registration during playback. Advantages of the technique include: compact movie storage, ease of replication of movies, simple projection system and slow-motion capability.
