Holographic motion pictures and video
Graham Saxby · 2003
The simplest kind of ‘movie’ is a holographic stereogram in which the horizontal parallax has been wholly or partly taken over by movement. In the earlier examples the subject would make some simple movement or gesture during the shooting of the originating photography. An early example of this was Lloyd Cross’s 1208 cylindrical stereogram ‘Kiss’ in which the image of Pam Brazier blows a kiss and winks as the viewpoint moves from left to right (Fig. 19.5). In these stereograms, shot initially with a cine camera, only a simple brief gesture was possible, and this had to be carried out with exaggerated slowness (most viewers move past a 1208 stereogram in about 3 seconds, but the image would have taken 15 seconds to shoot). A large number of stereograms have been made directly from movie sequences shot using a stationary camera. Some of these were made into 3608 cylinders that were set up to rotate slowly; others were wound slowly between two spools. Andrews and Rainsdon1 placed their time dimension in the vertical plane, by masking the temporally separated masters into horizontal strips, so that changing the viewing height animated the image. With this system it is possible to use vertical slit images to add horizontal parallax, but this demands a minimum of some 1000 images per hologram. Yamaguchi et al.2
