Abstract
A single flat sheet hologram is provided which when illuminated displays substantially a 360.degree. view of an object space. This is done by recording both left and right hand views of the object space on the single sheet of sensitive material. A flat sheet hologram composed of two emulsions, one recording the left side view and the other the right side view is also claimed. The views on these two holograms are coordinated so as to fix the corresponding points in space.
