提出一种双边缘结构对光纤光栅传感进行波长解调的方案，利用被测光谱通过不同光谱特性的滤波器时输出不同光强的比值确定被测光的波长．该系统在解调时不存在任何机械移动部分，比扫描式的解调方法测量速度更快，运行时更稳定、更精确．

High-Speed double-edged Wavelength Interrogation Technology for fiber Bragg grating sensor array was proposed,which employed the logarithm of the output ratio between the adjacent two channel of arrayed waveguide grating to determine the measured wavelength. This system permitted a fast and simultaneous interrogation of multiple wavelengths without any mechanically moving parts. The thesis mainly demonstrated the feasibility of this interrogation project in theory and experiment.
