Scientific paper

The paper reviews the geometrical theory of diffraction and telescope stray-light analysis. The control of diffraction effects in telescopes affects the optical design for which the geometrical theory of diffraction provides a computational tool. The nature of the geometrical theory of diffraction is reviewed, and its application to telescope diffraction problems, circular aperture diffraction, the barrel baffle diffraction are discussed. It is shown that the geometrical theory of diffraction provides a useful conceptual picture of the diffraction process, especially for multiple diffraction processes. The importance and sizes of telescope stops required to minimize diffraction effects in telescopes are discussed.
