ABSTRACT:
A shutterless hologram movie apparatus using an incoherent (non-laser) light source in the viewing apparatus. Image immobilization and dispersion compensation are both accomplished with the same reference beam-forming optics. The hologram film is imaged onto the exit pupil by means of a converging lens or mirror in the vicinity of the image. As the hologram film is drawn vertically across the reference beam, horizontal time frame bands on the film scan the exit pupil, resulting in apparent motion of the image.
