3-D imagery and holograms of objects illuminated in white light

Abstract

Described is a method of obtaining holograms of 3-D objects illuminated in white light. First, a 3-D scene, illuminated in white light, is photographed through a fly's eye lens. If this photograph is projected through the same lens it yields a real 3-D image of the object directly. However, by using coherent light for projection, this real image can be used to make a hologram, which in turn yields both a real and a virtual image of the object. © 1967 The American Institute of Physics.
