An Optical Fiber Liquid Level Sensor Based on Side Coupling Induction Technology
An optical fiber liquid level sensor based on two twisted polymer optical fibers twining around a racetrack column is demonstrated in this study. The side-coupling power of the passive fiber is modulated by the refractive index (RI) of the environment medium and decreases while the liquid level incr...
