Abstract Computational neuroscience has been widely used in fiber optic sensor signal output. This paper introduces a method for processing the Surface Roughness Fiber Optic Sensor output signals with a radial basis function neural network. The output signal of the sensor and the laser intensity signal as the light source are added to the input of the RBF neural network at the same time, and with the ability of the RBF neural network to approach the non-linear function with arbitrary precision, to achieve the nonlinear compensation of the sensor and reduction of the effect of changes in laser output light intensity at the same time. The Surface Roughness Fiber Optic Sensor adopting this method has low requirements on the stability of the output power of laser, featuring large measuring range, high accuracy, good repeatability, measuring of special surfaces such as minor area, and the bottom surface of holed etc. The measurements were given and various factors that affect the measurement were analyzed and discussed.

A dual fiber-optic sensor for the simultaneous determination of bromide and iodide is successfully demonstrated. The device is based upon the dependence of quenching effects on individual fluorophores (quinine and harmane) and quenchers (bromide and iodide). From the point of view of practical application, n unknown analyte species should be able to be determined with a sensor array which contains n sensor elements on which n fluorophores are immobilized. The relative error of the new sensors for the determination of bromide and iodide is less than 5%. The sensor combination is reversible and exhibits an overall response time of 2 minutes. The interference of several ions on the sensors has been studied.
