【摘要】 本文阐述一种新型光纤光栅应变传感技术,利用光通信领域成熟的DWDM技术作为光纤光栅调制技术,可以实现多通道应变传感网络技术。DWDM解调技术利用DWDM的滤波曲线和波分复用技术可以实现多通道动态解调。通过对DWDM光纤光栅解调技术的研究,能够实现基于应变测试的应变、应力、加速度、压强等光纤光栅静态和动态智能化传感技术完整解决方案。更多还原

【Abstract】 The article expatiated a new FBG strain sensor technology, which use the matured DWDM technology in optical communication field as the modulate technology for FBG and can realize multichannel sensor network technology. The DWDW demodulate technology which use the DWDM filter curve and wavelength division multiplex technology can realize multichannel dynamic demodulate. Through the research of DWDM FBG demodulate technology, we can realize FBG static and dynamic intellectual sensor technology solution such as strain, stress, acceleration, pressure and so on based on strain test.更多还原
