Abstract

In this paper we suggest that a one-dimensional grating may be employed in place of the random diffuse screen and slit used in one-step, two-dimensional rainbow holography. A demonstration of this slitless rainbow holography is given by means of Fourier optics. Holograms fabricated in this manner in a 4f-like processing system prove to be satisfactory. This slitless rainbow holographic system is energy saving and hence remarkably reduces exposure time. One-dimensional diffuse screens can also be used in the same way as the grating.
