Sequential and non-sequential field tracing

[Friday, 11. May 2018]

 

With the release of the non-sequential extension, VirtualLab is now capable of performing System Analysis with Sequential and Non-Sequential Field Tracing.

This new feature greatly simplifies the construction and analysis of certain types of optical systems, and enables many additional applications.

The Non-Sequential Configuration can be adjusted flexibly for various simulation tasks,

e.g., Investigation of Ghost-Image Effects in Collimation Systems,

or Modeling of Etalon with Planar and Curved Surfaces.

Thanks to the non-sequential field tracing technique, multi-path optical systems can be constructed and modeled much more conveniently.

Some examples of such systems are the Herrig Schiefspiegler Telescope,

Offner systems,

and interferometers, like the Mach-Zehnder.

As a result, many practical applications based on multi-path interference effect can be easily analyzed.

For example, the optical topography scanning with a Michelson interferometer,

or the Examination of Sodium D Lines with Etalon, are demonstrated in VirtualLab.

Furthermore, non-sequential field tracing plays an indispensable role for the modeling and design of waveguide-based near-eye-display (NED) systems. The folding of light paths and the extension of the exit pupil in such systems,

are achieved with Light Propagation through Waveguide with In- & Outcoupling Surface Gratings.

The same as with the etalon, VirtualLab facilitates the Analysis of Folded Imaging System with Planar or Curved Waveguide.
