Partial coherence interferometry
WebThe IOL Master 500 uses the principle of partial coherence interferometry, and its successor, the IOL Master 700, incorporates optical coherence tomography. 14,15 Both … WebTopological insulator surfaces in proximity to superconductors have been proposed as a way to produce Majorana fermions in condensed matter physics. One of the simplest proposed experiments with such a system is Majorana interferometry. Here we consider two possibly conflicting constraints on the size of such an interferometer. Coupling of a …
