摘要： A method of manufacturing a perovskite multilayered structure includes providing a substrate, forming a first perovskite layer on the substrate, forming a second perovskite layer by a reaction between the halogen compounds and at least one of the metal halides, the metal oxides, or the metal sulfides.

摘要： Embodiments relate to a dual Brillouin distributed optical fiber sensing system and a sensing method using Brillouin scattering that detects an event area in which an event occurred quickly by simultaneously measuring multiple correlation points located in an optical fiber under test by using a pump signal modulated with a pulsed gating signal and a continuous wave probe signal, and then precisely measures the corresponding event area by using the probe signal modulated with the pulsed gating signal and the pump signal.
