ABSTRACT:
An apparatus for constructing a hologram of one or more two-dimensional images by displaying the images on a variable-reflectance device. An object beam of coherent radiation is directed at the variable-reflectance device to be redirected by the device to a holographic plate, and a reference beam of coherent radiation is directed at the holographic plate to produce, in combination with the redirected object beam, a holographic interference pattern on the plate to form a hologram on the plate. A masking device, preferably electronic, may be provided to selectively expose successive portions of the plate corresponding to successive ones of the images to form a multiplex hologram on the plate.
