Diffraction patterns of simple apertures

- Richard C. Smith, J. S. Marsh
- Physics
- 1 June 1974

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

Contour plots using a moiré technique

- J. S. Marsh

- PhysicsElectronic Imaging
- 12 April 1995

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

Magnetic and electric fields of rotating charge distributions II.

- J. S. Marsh
- Physics, Chemistry
- 1982

A charge distribution with axial symmetry is allowed to rotate with constant angular velocity around the axis of symmetry. The magnetic field of the resultant current density is calculated in terms… Expand

This paper describes Abstract This paper describes the use of Lloyd's mirror in two optical processing applications. First it is shown that if the narrow slit in the usual Lloyd's mirror set up is… Expand

Light distribution near the focal point of a two‐dimensional lens

- J. S. Marsh
- Physics
- 1 February 1984

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

Computer Holograms With a Desk-Top Calculator.

- J. S. Marsh, Richard C. Smith
- Physics
- 1 August 1976

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
