Generalized Beams in Abcdgh Systems

Abstract

For a generalized beam at the source plane passing through co-located aperture and a propagation path consisting of an off-axis x-y asymmetric ABCDGH system, the receiver plane irradiance expression is derived using the Collins integral. A collection of source beam profiles that are obtainable from the generalized. beam formulation are illustrated. Plots are given for viewing the progress of selected generalized beam types along the propagation axis, containing a single thin lens, co-centric and misaligned in the x-direction. The received power failing onto a finite aperture surface is calculated for various misalignment situations. (c) 2006 Elsevier B.V. All rights reserved.
