Abstract
A sensor comprises an optical sensor fiber which has a microbend module engaged thereto. When the module is subjected to external influences such as pressure, displacement or the like, it places microbends in the sensor fiber which changes a light transmission characteristic of the fiber. Light passing through the sensor fiber is detected, and changes in the light are measured to find the influence on the modulator. A scintillating or florescent source fiber connected to one end of the sensor fiber is exposed to radiant energy. This produces light which is channeled to the sensor fiber as the light source for the sensor fiber.
