Paper Abstract

In this work half the length of the single FBG is chemically etched and the un-etched half is glued on a cantilever. The response of the grating is investigated as a function for buoyancy force on the cantilever due to liquid level and temperature. Simultaneous measurement of liquid level and temperature is achieved from the coefficients of liquid level and temperature sensitivities obtained from the experimental results.
