Fourier Transform Spectroscopy

Fourier Transform spectroscopy – an optical metrology method that can be used to measure the optical spectrum of a source with a Michelson interferometer – is a
well-known technique commonly used in a wide range of applications that can go from investigating air or water quality to pharmaceutical analysis.

To help the optical designer understand all the effects that can play a role in such devices, the fast physical optics software VirtualLab Fusion provides all the necessary tools to perform a full propagation through these systems. This naturally includes all coherence and interference effects that are happening at the detector plane. Furthermore, through our new Detector Add-Ons, the user has access to all physical quantities that are of interest, such as irradiance or radiant flux.

Please take a look at the links below to find an example where the temporal coherence length of a polychromatic source is investigated through a Michelson interferometer, as well as some thorough documentation of our Detector Add-Ons.
