WebAn interferometer records the interference fringes created by combining the light from two or more telescopes. Basic measurements are the amplitude (or height) of the fringes and … WebIn this chapter the basic principles of interferometry are reviewed with an empha- sis on the common features for radio and optical observing. While many techniques are common to interferometers of all wavelengths, crucial differences are identified that will help new practitioners to avoid unnecessary confusion and common pitfalls.
