WebA basic interferometer creates two beams from one source and sets up an interference pattern by combining a fixed reference path with a moving test path at the detector. Coherence between two waves refers to the ability of the waves to interfere with each other in an observable way. WebAug 10, 2024 · High resolution. SU (1,1) interferometers are a new type of quantum interferometers, which are quite different from the traditional interferometers in that the linear beam splitters are replaced by nonlinear optical devices of parametric amplifiers (PAs), as shown in Fig. 1 (b). The name of SU (1,1) stems from the type of interaction … WebBasics of Optical Interferometry (Observationnal Astronomy II) Lecture by Stéphane Sacuto.
