(An optical fibre evanescent field sensor for methanol
(CH3OH) and ethanol (C2H5OH) solvents based on deformed optical
fibre cores is reported. The sensitivity of an existing U-bend
probe is increased by extending the exposed core to a coil shape
of one and a half turns and by forming the core to a meander
shape with three bends. Using the visible wavelength area (VIS)
and methanol/ethanol concentrations from 0 to 10 it is shown
that the sensitivity of the meander shape sensor enables the determination
of methanol concentrations of better than 0:5 and of
ethanol concentrations of better than 0:2 at 650nm. This facilitates
the use of low cost optical sources and receivers provided for
this wavelength range as well as the utilization of polymer optical
fibres to guide the light to and from the sensor which results in low
cost applications compared to all silica or polymer clad silica fibre
solutions in the near-infrared (NIR) or ultra-violet (UV) wavelength
range.)
