摘　　要：光纤光栅点式水压传感器是应用光纤受外力变形时,射入光纤的紫外激光的波长会发生改变并被光栅反射回来原理,利用光栅变形传感器相对某一点水压力的瞬时压力值测试,扩展光纤光栅传感器的种类和应用。布喇格(Bragg)光纤光栅作为传感元件具有灵敏度高、性能稳定、抗干扰能力强(完全不受强电磁信号的干扰)、体积小、寿命长、结构简单可靠等优点,具有极其广泛的应用前景。The fiber grating and point supported water pressure sensor has used grating deformation sensing that relative to the instantaneous pressure value of certain point of water pressure, which has expanded the type and application of fiber grating sensor. The fiber optical Bragg grating has many advantages such as high sensitivity, steady performance, strong anti interference ability （completely without the interference of strong electromagnetic signal）, small volume, long life and simple and reliable structure, which has widely application prospect.
