Modeling Pinhole Diffraction within System

[June 21, 2020]
We demonstrate the modeling of pinhole as well as surface aperture diffraction effects inside a low-Fresnel-number system, and compare the results with the typical exit pupil diffraction approach.
[June 21, 2020]

Diffraction effects are typically considered only at the exit pupil of a system and including intra-system diffraction (especially when it is caused by multiple truncations), as discussed by M. Mout et al., is a challenging task. With the innovations in Fourier transforms, you have direct and flexible control of the diffraction inclusion in VirtualLab Fusion 2020.1. As an example, we demonstrate the modeling of pinhole as well as surface aperture diffraction effects inside a low-Fresnel-number system, and compare the results with the typical exit pupil diffraction approach.

Automatize Your Simulation Tasks

[June 05, 2020]
For the analysis of modern optical devices and systems, engineers often need to execute a large amount of simulations. To assist with such tasks, VirtualLab Fusion provides a flexible inbuilt programming language. It is possible to access VirtualLab Fusion simulations externally, giving you the full possibility to further analyze the simulation results.
[June 05, 2020]

For the analysis of modern optical devices and systems, engineers often need to execute a large amount of simulations to gather and sort the results, so as to fully study the optical design. To assist with such tasks, VirtualLab Fusion provides a flexible inbuilt programming language, which allows, for example, for the automatic saving of the simulation results. Moreover, it is possible to access VirtualLab Fusion simulations externally (via MATLAB or Python), giving you the full possibility to further analyze the simulation results.

Generation of Non-Diffracting Bessel Beams

[May 19, 2020]
We demonstrate how to generate Bessel beams with an axicon, and, following the research work of O. Brzobohatý et al., we investigate how the round tip of the axicon may influence the resulting Bessel beam.
[May 19, 2020]

Nowadays, Bessel-like beams and similar kinds of non-diffracting beams are not just generated in the lab but have been put to use in different applications. To better exploit such beams, their properties must be studied and understood more deeply. As a typical example, we demonstrate how to generate Bessel beams with an axicon, and, following the research work of O. Brzobohatý et al., we investigate how the round tip of the axicon may influence the resulting Bessel beam.

Optical Metrology with Interferometry

[April 30, 2020]
VirtualLab Fusion can help you build up various types of interferometers and include the different optical surfaces and components of the system, and even alignment mistakes like tilt and shift, in the simulation.
[April 30, 2020]

Optical metrology is an essential technology for precise measurement. For example, it is often used for surface testing and therefore plays an important role in quality control. VirtualLab Fusion can help you build up various types of interferometers and include the different optical surfaces and components of the system, and even alignment mistakes like tilt and shift, in the simulation. Two widely used interferometers – Mach-Zehnder and Fizeau – are demonstrated as examples.

Collimation Testing with Shearing Interferometry

[April 24, 2020]
In VirtualLab Fusion we can model the multiple interaction between light and the shear plate easily with the help of the channel concept.
[April 24, 2020]

How well is a beam collimated? This is an essential question for many optics, especially in laser applications. Shearing interferometry is a simple and convenient way to test beam collimation quality, and we demonstrate this in VirtualLab Fusion. The key device in the interferometer is a shear plate, with high-quality flat surfaces and usually with a small wedge angle. We can model the multiple interactions between light and the shear plate easily with the help of the channel concept in VirtualLab Fusion.
