Abstract
An apparatus, method and system are provided for scanning documents, and creating holographic and panoramic images. The apparatus provides two sets of prisms, one set of which is made of electro-optical material. The prisms are arranged in alternating rows to form a sheet. The prism sheet can be laid flat or rolled into a cylinder. A sequencer is used to activate individual electro-optical prisms so that the image is reflected into the sheet. A second prism is used to reflect the image into an image receptor such as a camera. By sequentially activating the electro-optical prisms, successive image portions of an object or objects can be presented to the image receptor. If the image receptor accepts digital input, the sequential images can be post-processed in a microprocessor to create a holographic or panoramic image. Similarly, images of documents can also be scanned and the images received can be digitized for processing, storage and/or transmission. The prism sheet is flexible and can be rolled into a variety of shapes for creating holograms or scanning panoramic images. Moreover, the prisms can be curved, allowing prism sheets to be shaped into spheres or conic sections.
