A unique method for the construction and display of a 3-D
holographic movie is developed. An animated film is produced by rotating
a 3-D object in steps between successive holographic 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 2 deg between successive exposures. A complete cycle of the
object motion 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,
as predicted by the theoretical analysis. The movie can be viewed for an
unlimited time 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 3-D effect. Viewers can stand comfortably
away from the film since no viewing slit or aperture is necessary.
Several people can simultaneously view the movie.
