“…Optical sensor with a FPI method was also developed for various applications such as pressure measurement [13], humidity sensor [7,14], liquid level measurement [15], temperature and strain sensor [16], acoustic emissions measurement [17], and gas detection [18]. However, the FPIbased optical sensor for the detection of cadmium ion has not been fully explored.…”

Abstract-Optical sensors based on Fabry-Perot interferometer to detect cadmium ions is proposed. The sensor was fabricated by coating the tip of the optical fiber by chitosan. The two chitosan surfaces serve as mirrors which form a Fabry-Perot interferometer. The characterization results indicate that the sensor has a linear response with sensitivity of 0.0884 dBm/ppm with a correlation factor of 0.9665. The sensor reach steady state response in 5 minutes.

“…An independent temperature calibration followed by straining sensor was used to demonstrate simultaneous monitoring of strain and temperature. Li et al [28] reported on a hydrofluoric acid-etched intrinsic Fabry-Perot (FP) cavity in conjunction with an FBG to enable simultaneous monitoring of strain and temperature. The strain and temperature sensitivities of the Fabry-Perot cavity and the FBG were established independently.…”

a b s t r a c tThis paper reports on the design, fabrication, characterisation and deployment of a multi-measurand optical fibre sensor (MMS) that is capable of simultaneously monitoring strain, temperature, refractive index and cross-linking chemistry. The sensor design is based on the extrinsic fibre Fabry-Perot interferometer. A feature of this sensor system is that a conventional multi-channel fibre-coupled near-infrared spectrometer is used to monitor the four independent parameters. The issues relating to the measurement resolution of the individual sensors and the associated interrogation equipment are discussed. The MMS was embedded in between the fourth and fifth plies of an eight-ply E-glass plain-weave fabric. A commercially available thermosetting epoxy/amine resin system was used to impregnate the fabric layers manually. The laminated preform was vacuum-bagged and cured in an autoclave. The following parameters were monitored: the depletion rates of the epoxy and amine functional groups in the resin system; the temperature in close proximity to the "chemical sensor"; the evolution of strain; and the refractive index of the resin system. The effect of post-processing on the output from the embedded optical fibre sensors is also considered.

“…And charged particles in laser plasma also can produce electromagnetic interference to relegate measurement precision. Fiber optic sensors have the advantages of erosion resistance, small size, immunity from the disturbance of electric and magnetic fields, intrinsically safe [11][12][13][14]. The characteristic of immunity to electric and magnetic fields made fiber optic an appropriate substrate which could avoid the electro-magnetic disruptive influences from charged particles in laser plasma.…”
