Abstract

Holographic movies can be seen as a tool to estimate the picture quality of moving holographic images as a step towards holographic television. As a step towards the development of truly practical holographic movies, we have built an improved experimental holographic movie system and produced short duration holographic 3D films. In the improved system, various objects were positioned within a scene and illuminated with He-Ne lasers (632.8 nm). Conventional film-making techniques were adopted during the holographic recordings to create a more attractive sequence. These techniques included stop-motion, tracking, up-shots, overlaps, and pans. A series of Fresnel type frame holograms was recorded on perforated 35 mm holographic film. An interesting technical point is that the frame holograms were 12 mm high by 122 mm wide at maximum, and consisted of two diamond- shaped elemental holograms, one for the left eye and one for the right. Frame holograms were recorded diagonally at an angle of 10 degrees of the film to reduce the film driving length. After developing, the films were driven intermittently with a shutter, and the films were illuminated by the same type of laser as that used in the recording. The films were viewed through a pair of diamond-shaped windows, and the display speed could be varied from 8 to 16 frames per second.
