The Fraunhofer diffraction patterns of the triangle, trapezoid, and hexagon are calculated and displayed in moire plots. The diffraction pattern of the general polygonal aperture with a finite number… Expand

A simple method utilizing a moire technique for producing contour plots is described and applied to the rendering of calculated Fraunhofer diffraction patterns.

Cylindrical holography has been utilized to capture 180 degree(s) field of view of high speed ballistic events. In this paper, we detail the methodology, design, and experimental results for a… Expand

The distribution of light in the focal region of a lens in two dimensions is calculated in terms of the Fresnel integral. The result is a comparatively simple but very good analog for the focal… Expand

The expression is used as the basis of a quantitative discussion of Hennessy's informal experiment and Roscoe's zoom lens hypothesis and data obtained by Biersdorf and Baird agree with it.Expand

Computer‐generated holograms have been produced on the plotter of an HP 9100B desk‐top calculator. The use of simple stick objects allows us to calculate analytically the Fourier transform, the… Expand

The holographic image equations are interpreted in a way that clarifies the meaning of stereo pairs of holographic images and indicates how backprojection methods can be used in holography to locate objects.Expand
