Abstract

Although the two-step holographic technique for producing white-light-transmission, or "rainbow", holograms has proven the most practical for producing display images, one-step apertured-lens techniques can also be useful in producing such holograms. Typically, the diameter of the lens limits the field of view, but not the image size, for pseudoscopic image presentation, or imposes an intermediate vignetting aperture in the orthoscopic case. Here we describe how the combination of conjugate wavefront illumination and conjugate diffraction can be used to produce a large-area, undistorted, orthoscopic image, with only the field of view limited by the lens size. The resulting holograms enjoy very high image contrast, and rival the results of the two-step process in many respects.
