How interferometry works

Web18 nov. 2024 · Interferometers can measure objects with extreme accuracy. They work by taking a beam of light and splitting it into two equal halves using a beam splitter, effectively a piece of glass thinly coated with silver. When light is shone on the beam splitter, half the light passes through and half is reflected back. WebInterferometry (in this case “astronomical interferometry”) is a technique that astronomers use to obtain the resolution of a large telescope by using multiple smaller telescopes. …
