Abstract
A liquid-level sensor based on the refractive-index sensitivity of long-period
fiber-optic gratings is proposed and demonstrated. The form of the transmission
spectrum of the long-period grating is dependent on the fraction of the length
of the long-period grating that is surrounded by the liquid. The sensor shows
a large linear range, with sensitivity of 4.8% change in transmission per
millimeter, for a long-period grating with a length of 40 mm
and a periodicity of .
