A two-dimensional, white light illuminable arcuate rainbow hologram that is potentially viewable from 360.degree. is formed by limiting the information content of a wave front representing a reflection of monochromatic coherent light off of the object desired to be holographed. The information content is limited to a selected portion of the wave front, the selected portion passing through or upon an arcuate window which preserves the selected portion. The arcuate window is formed using an arcuate aperture, a flat arcuate master hologram, or a cylindrical shell of laser light used as a reference beam. The arcuate rainbow hologram is viewable from 360.degree. if the arcuate window is annular, i.e. circular. If the window is a half-circle or other arc angle, the window of viewability will correspond to the angle of the arcuate window that limits the information content of the wave front representing the reflection of monochromatic coherent light off of the object to be holographed. The arcuate rainbow hologram may also be multiplexed, where the "object" is a set of two-dimensional images of a subject from different perspectives.
