Abstract

We present two configurations of new fiber optic Bragg grating sensor developed for petroleum hydrocarbon detection. The sensor includes FBG attached to the special polymer swelling in the hydrocarbon presence. This polymer reversibly strains the fiber section with the Bragg grating inside. The first sensor configuration employs a single grating and standard demodulation technique to determine a strain induced shift of the Bragg wavelength. The second sensor configuration make a use of double grating interferometric sensor consisting of a reference grating free from axial strain and a sensitive one, attached to the polymer. A new demodulation technique is based on monitoring of energy of the interference term in the reflection spectrum. We demonstrated experimentally that such configuration is free from temperature influence. The paper presents the results of the swelling-behavior test of the sensitive polymer material and the results of the experimental investigation of the hydrocarbon sensor performance.
