摘要
Within the framework of diffraction theory, we investigate some closed-form propagation expressions of flattened Gaussian beams through a paraxial optical ABCD system. By studying the propagation through an aperture, we have derived the closed-form propagation expressions through an ABCD system as a limit when the aperture width is infinite. The closed-form propagation expressions are derived, as a function of the Gaussian probability function, which relates the electromagnetic fields on the input plane to those on its output plane. Some numerical examples are also illustrated. (C) 2001 Elsevier Science B.V. All rights reserved.
