Fourier Transform Settings
Discussion at Examples
Abstract
Many field solvers and functions are included in VirtualLab Fusion. They may either working in the space (x) domain or the spatial frequency (k) domain. To use different solvers and functions in connection, so to enable the modeling of complex systems, the transforming between x and k domain is a crucial step. Three Fourier transform algorithms are available in VirtualLab Fusion, and, with this document, we show how to set the options by discussing at different examples.

Use Case
Pinhole Modeling in a Low-Fresnel-Number System
With the flexible Fourier transform settings in VirtualLab Fusion, we model the diffraction effect from surface apertures and pinholes in a low-Fresnel-number system.
Use Case
Collimation Testing with Shearing Interferometry
We show how to build up a shearing interferometer for the testing of laser beam collimation. By changing the collimation lens system, we observe the change in the interference fringes.
Use Case
Afocal Systems for Laser Guide Stars
Within VirtualLab Fusion, we demonstrate the analyze afocal systems for the generation of laser guide stars, and further optimize the system to control the size of the artificial stars.
