This paper presents a unique approach to the production and display of a hologram movie. Motion was provided by rotating a 3D object in steps between exposures. Strip holograms were made on 70 mm AGFA 8E75 Holotest roll film. Each hologram was about 11 mm high and 55 mm wide. The object was rotated two degrees, while the film was advanced, between successive exposures. A complete rotation of the object was recorded on 180 holograms using the lensless Fourier-transform construction. The ends of the developed film were spliced together to produce a continuous loop. Although the film moves continuously on playback and there is no shutter, there is no flicker or image displacement because of the Fourier-transform hologram construction. The movie can be viewed for as long a time as desired because the object motion is cyclical and the film is continuous. The film is wide enough such that comfortable viewing with both eyes is possible, enhancing the 3D experience. Viewers can stand comfortably away from the film since no viewing slit or aperture is necessary. Several people can view the movie at the same time. Speckle is reduced due to the film motion.
