Development and characterization of a fiber Bragg grating ethanol sensor for liquids

• Abstract:

  This paper reports some very first results about the development and the metrological evaluation of a fiber Bragg grating (FBG) ethanol sensor, able to work into liquid solutions. The sensing device is established by dip-coating a single-mode silica FBG with a poly(methyl methacrylate) (PMMA) coating film. The thickness of the sensing coating was set by means of a deposition system able to control the rising/dipping rate of the FBG in the PMMA solution. Tests were performed in a range spanning from 3 % to 40 % in v/v of ethanol in water in order to investigate the device response. In particular, dynamic performance in terms of response and recovery time values were also estimated.
