A new approach to the modeling of optical remote sensing systems using vortical scattering parameters

摘要

The application of scattering matrix theory in optics has usually been limited to multilayer propagation of plane waves but the analysis of spatial diffraction, the most characteristic effect of any optical element, has had to be considered through techniques much less competent. This paper describes the use of a generalized modal scattering matrix theory as a fast, efficient approach to the analysis of optical systems. In contrast with other methods, the new technique uses a type of optical vortices, called Bessel beams. This rigorous modelling technique has interest in areas of optics as diverse as optical communications, spectrometry, and remote sensing systems. The tactic allows solving both multilayered reflections problems and spatial diffraction phenomena using scattering parameters associated with the transmitted and reflected vortical spectrum.
