Light Diffusing Optical Fiber Sensor for Distributed Optical Absorption Spectroscopy and Chemical Sensing

An optical fiber sensor system for distributed optical absorption spectroscopy based on light diffusing optical fiber is proposed and evaluated. The sensor is composed by two light-diffusing glass fibers radiatively coupled. The light from a pulsed laser diode propagates along the first fiber and is locally diffused out into the medium between the fibers. The light transmitted by the medium is partially collected by the second fiber and detected at the end of the fiber by an optical time domain reflectometry detection scheme. The system permits distributed measurements of the optical absorption properties of the sample medium between the fibers. The experimental results confirm the possibility of distributed measurements with a spatial resolution of about 17cm over 4m of measurement range. Distributed chemical sensing has been also evaluated by measuring the absorption of water solutions containing copper ions. A limit of detection of 710ppm has been achieved.

“…The SPR sensor made of surface plasmon resonance can subtly detect the change in the refractive index of the sensing medium. SPR sensors can be used to directly measure RI or indirectly detect any physical factor causing RI changes, such as temperature, concentration, strain, magnetic field, pressure, density, and molecular species [ 5 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ].…”

Temperature sensors have been widely applied in daily life and production, but little attention has been paid to the research on temperature sensors based on surface plasmon resonance (SPR) sensors. Therefore, an SPR temperature sensor with a triple structure of titanium dioxide (TiO2) film, gold (Au) film, and TiO2 nanorods is proposed in this article. By optimizing the thickness and structure of TiO2 film and nanorods and Au film, it is found that the sensitivity of the SPR temperature sensor can achieve 6038.53 nm/RIU and the detection temperature sensitivity is −2.40 nm/°C. According to the results, the sensitivity of the optimized sensor is 77.81% higher than that of the sensor with pure Au film, which is attributed to the TiO2(film)-Au-TiO2(nanorods) structure. Moreover, there is a good linear correlation (greater than 0.99) between temperature and resonance wavelength in the range from 0 °C to 60 °C, which can ensure the detection resolution. The high sensitivity, FOM, and detection resolution indicate that the proposed SPR sensor has a promising application in temperature monitoring.
