Paper Abstract

Fundamental properties and particularities ofthe Gabor's,Leith-Upatnieks's and Denisjuk's holograms are well . TheBenton's rainbow hologram excites great interest .Benton's rainbow holography is a two-step process of hologramrecording where a narrow aperture slit is introduced into the second stage.One-step schemes for rainbow holography (RH) were proposed later on. A narrow aperture slit restricting object wave is an inherent component ofthe existing schemes of one- and two-step recording schemes. The aperture slit in RI-I recording schemes is the main disadvantage of RH method because it increases exposures 1 00 tol 000 times and prevents applications ofthis method in real time interferometry.. The united hologram uniting the Gabor's, Leith-Upatniecs's and Benton's holograms in one is considering in this report. This is the slitless method of RH recording. The report summarizes slitless one- and two-step methods ofRH recording. The narrow aperture slit is excluded in the slitless method of RI-I recording through application of the second reference wave coaxial with the object one. As a result, three holograms are being recorded simultaneously on a photographic plate: an axial Gabor's hologram, an off-axial Fresnel's hologram and a regular holographic grating (RHG), moreover, the off-axis and RHG possess the same spatial frequency. Existence of a RHG in a hologram is the cause of new features: object image is reconstructed in rainbow colours when such a hologram is illuminated with white light ;when it is illuminated with laser light a number of new object images. The report also shows the common physical nature of the phenomena that seems at first rather distant from each other: of rainbow holography and the Talbot effect in holography, and it proposes a theory of slitless RH and of the Talbot effect in holography developed from a unified point of view.
