Simulation Research about Signals Processing of Optic Fiber Sensor Array Sensitive to Heavy Metal Ions

Abstract:

Considering the approximation between Gaussian function and spectrum, Gaussian function is utilized to simulate the spectrum of optical fiber sensor array sensitive to four heavy metal ions. The division of superimposed spectrum in measurement by optical fiber sensor array and the analysis of relative error are simulated by Matlab software. From the simulation, it is known that the superposition error of spectrum caused by interference between four ions in films sensitive to heavy metal ions can be reduced with corresponding arithmetic, which provides good theoretical foundation for preparation of optical fiber sensor array and signals processing of spectrum.
