Coherence Effects on Holographic Interferometry
The effects of spatial coherence on the characteristics of the reconstructed image in two—beam holography are considered taking into account the spatial coherence of the reference beam itself. On the basis of this consideration, the properties of the interference fringes on the image of a time—varying diffuse object from the, hologram recorded and reconstructed with partially spatial coherent light by double exposure method are investigated. The characteristics of both image formation and fringe formation depend on the spatial coherence and the optical arrangement. It is shown that high—visibility fringes can be obtained by image holography.
