Abstract

An all optical fiber, intensity modulated sensor for discrete liquid level sensing is presented. The highly sensitive and robust design requires only silica fibers, an optical source and a detector. The sensor probe is prepared by etching the silica fibers using hydrofluoric acid. Experiments conducted with water confirm the ability of the sensor to detect liquid level variation below 10 μm. © 2010 Wiley Periodicals, Inc.

## Abstract We present a new bend sensor which can measure the curvature using an etched fiber Bragg grating (FBG) embedded into a beam. The reflection power of the grating detected by an optical power meter varies linearly with the curvature of the beam. This sensor is independent of temperature.

## Abstract A new fiber‐optic liquid‐level sensor (LLS) for continuous monitoring of the liquid level is proposed using a fiber‐optic displacement sensor (FODS). A float is used to measure the level of liquid in the tank and it is connected to the FODS probe to convert the variation of the liquid l
