光纤布拉格光栅数据采集系统研究

Research on fiber Bragg grating data acquisition system

为了能使光学传感器在部队得到广泛的应用,以提高武器系统的打击精准度,通过研究光纤光栅传感器,并且针对光纤布拉格光栅解调系统中数据采集速度高的问题,提出了一种利用高性能微控制器ARM(advanced RISC machine)和复杂可编程逻辑器件(CPLD)来设计采集电路的方案,并给出了主要环节电路的软硬件设计。这一设计能很好满足解调系统要求。

In order to apply the optic sensor broadly in the army to improve strike precision of the weapon system, this paper research the fiber grating sensor and gives an approach to the data acquisition circuit of the fiber Bragg grating demodulating system. The system is based on high-performance ARM microprocessor and complex programmable logic device （CPLD）. The main hardware and software design represented in this paper. This design is able to satisfy the demand of the optics demodulating system commendably.
