"WebAug 1, 2024 · To see the interference, the light goes through a pinhole that is multiple wavelengths wide. The light spreads out in all directions, and when it hits a flat wall anywhere but the center, the light that went through different parts of the hole will have traveled different distances. So it interferes. All that matters is the geometry. " - How does interferometry work

WebJul 7, 2024 · The working principle of Interferometry technology consists on a splitting of the light into two beams that travel different optical paths and are then combined to produce interference. Interferometric objectives allow the microscope to operate as interferometer; fringes are observed in the sample when it is in focus. WebAug 18, 2024 · A laser interferometer measures the resulting distance by splitting a laser beam into two, sending each of the two beams along different directions in space (each along one of the two arms of the detector), and then recombining the beams. If the beams travelled exactly the same distance, then a detector detecting the recombined beam will …
