Imaging and Fourier transform properties of an all-spherical-mirror system
Abstract
An all-spherical-mirror system for applications in coherent image processing is described and analyzed. This one-to-one system is panchromatic and can be made to have minimal cosmetic defects. Such a system offers advantages such as multiple wavelength operations and the introduction of minimal scattering noise into the final image. A sample design that is diffraction-limited (for f/8) over the entire area of a standard 35-mm slide is given. The Fourier transform properties of this system are acceptable for many applications.
