Alternative Implementation of Simplified Brillouin Optical Correlation-Domain Reflectometry

We developed an alternative configuration of simplified Brillouin optical correlation-domain reflectometry, which can overcome the drawbacks of the original configuration. This system uses, as reference light, the light that is Fresnel reflected at a partial reflection point artificially produced ne...
