Optical Transformations In Three-Space: Simulations With A Pc, Raymond G. Wilson, Sean M. Mccreary, Jeffrey L. Thompson
Raymond Wilson
Using Fourier transform and convolution techniques, it is illustrated how all aspects of Fraunhofer diffraction of virtually any aperture real or complex can be calculated and displayed in two- and three-space using an IBM-compatible PC. Details of program commands using software Matlab are illustrated as well as results of plotting software Surfer. Fresnel diffraction is illustrated using Fourier transformation.

Ionic Polishing Of Fused Silica And Glass, Raymond Wilson
Raymond Wilson
This paper reviews research in the erosion of fused silica and glass in an effort to gain a better understanding of the ionic polishing process as applied to optical materials. Erosion rates depend on ion mass, ion energy, target temperature, angle of incidence, and target material, and can also depend on vacuum pressure. The paper also considers other effects that accompany ionic bombardment of insulators, such as nature of the eroded surface, contaminate films, surface layer alterations, secondary electron emission, and gas trapping and release.
