Abstract

This is a holographic technique for making a motion picture. A hologram, used as the movie film is made as shown. Mirror 12 has the shape of a conic section. It diverts part of collimated coherent light beam 14 to film 16. Film 16 is a band surrounding object 18 and concentric with object 18 and mirror 12. Light 20 reflected from object 18 strikes film 16 forming a ring hologram on it.

Ring Hologram for 3 D Display Single Concept Motion Picture

This is a holographic technique for making a motion picture. A hologram, used as the movie film is made as shown. Mirror 12 has the shape of a conic section. It diverts part of collimated coherent light beam 14 to film 16. Film 16 is a band surrounding object 18 and concentric with object 18 and mirror 12. Light 20 reflected from object 18 strikes film 16 forming a ring hologram on it.

The ring hologram can be displayed by illuminating with a conic section mirror. The reproduction is viewed from any position around 360 degrees. If the ring hologram is rotated, the reproduced object also rotates.

If the film is put on a reel and transported past the mirror, the result is a motion picture capable of being shown at any speed. Also, if the band is cut into a spiral and displayed in a motion picture viewer, the effect is that the object rotates while changing its vertical position.
