Optical interferometric setups are widely used for precise surface or wavefront testing and detailed analysis. Especially Fizeau interferometers are having pride of place as one of the most widely applied techniques for surface profile testing in the industry. We construct a testing optical system based on Fizeau interferometer in VirtualLab Fusion using several types of surfaces as test objects, and observe different interference fringes. Furthermore, a Mach-Zehnder interferometer for lens testing is presented as well.
Fizeau Interferometer for Optical Testing
A Fizeau interferometer is set up with the help of non-sequential field tracing technology, and the interference fringes from several different test surfaces are shown.
Mach-Zehnder Interferometer
We build up a Mach-Zehnder interferometer in VirtualLab Fusion, and demonstrate how the tilt and shift of components affect the interference fringe.
