摘　　要：为解决一个实际问题——实时监测船甲板微变形,提出了一个实际的系统方案。微弯调制的光纤、分路AD、优化算法等解决了系统实现的技术难点,从理论、试验及仿真等角度予以证明。从实用出发,给出了设计微弯调制光纤传感器的理论公式,提高弱信号SNR的算法以及递归求斜率的算法等。Ship on ocean, may be distorted for some reasons. Detecting its obliquity of distortion in time is helpful for controlling its pose. A scheme is presented in the article, which can match the practical precision and speed requirement of measurement. Practical formula and arithmetic are brought forward. Theoretical discussion, experimentation and emulation are introduced to indicate their feasibility.
