Paper Abstract

When a reflective surface is illuminated by a coherent light source, the far-field distribution of the reflected light is the Fourier transform of the surface. In this paper, we describe the far-field intensity distribution for various types of optical discs, and present some preliminary ideas for using the intensity distribution to derive information on parameters of interest. Further development of these ideas could lead to simple but powerful optical disc testers which do not need to focus and track on the disc surface.
