Holographic Ray Tracing and Spot Diagrams.
Abstract
A method is developed for computing spot diagrams of holographic images of point objects. The hologram is treated as an array of approximating gratings, and the spot diagrams are obtained by extending the emergent rays to planes in the region of the Gaussian image. Computed spot diagrams are given for one set of formation parameters where the reconstruction parameters have been varied to show the effects of slight to severe changes in reconstruction conditions. The parameters changed include variations x, y, and z coordinates of the reconstruction (reference) source and wavelength. Derivation of the new equations is given, and also a copy of a sample computer program is included. The spot diagrams were made using an automatic computer plotter. (Author)
