INTRINSIC FABRY-PEROT OPTICAL FIBER SENSORS AND THEIR MULTIPLEXING

摘要

An intrinsic Fabry-Perot optical sensor includes a thin film sandwichedbetween two fiber ends. In another embodiment, a portion of the cladding (320)of a fiber (310) is removed, creating two parallel surfaces. In a thirdembodiment, the refractive index of a small portion of a fiber is changedthrough exposure to a laser beam or other radiation.
