摘　　要：通过对双光纤光栅并联匹配解调原理的研究,提出了基于MSP430单片机的光纤光栅传感器解调系统。利用曲线拟合的方法对压电陶瓷驱动电压与光纤光栅的波长偏移量的数据进行拟合计算,实现光纤光栅解调的目的。本文给出了该方案软硬件设计,并对匹配解调法的发展前景进行了论述。A research of the principle of the parallel matching grating demodulation technique with double fiber grating leads to the propos of a demodulation system of fiber grating sensor based on the MSP430 Single-chip Microprocessor. By the synthetics curve method, the tiny offset of wavelength using the drive voltage of the piezoceramic actuator and the wavelength of the fiber grating is calculated; fiber grating demodulation is achieved. The design of hardware and soft- ware is given and the foreground of the matching demodulation method is discussed.
