Abstract
The current invention comprises the recording of full parallax, one-step, full color holographic stereograms so as to properly display the resultant imagery when the hologram is mounted on a curved substrate after recording. It also comprises mounting the hologram on a substrate that can be curved in one or two dimensions, thereby producing any arbitrary shape. The hologram is scalable, making it possible to create curved holograms of unlimited size. The hologram can be generated for application to one of a variety of curved substrates, including hemi-cylindrical substrates with opaque backing to allow up to 180 degrees of horizontal view zone, and full cylinders with transparent backing to allow viewing through 360 degrees horizontally. It also includes adaptation to conical, spherical, and other curved geometric and irregular topographies.
