摘　　要：针对空间环境参数测量的需求和特殊环境约束,研究光纤技术应用于空间飞行器上的系统性解决方案。从不同的参数敏感形式当中选择光纤光栅实现温度、压力等物理参数测量,详细分析了光纤光栅解调装置的设计与实现,采用CCSDS标准协议形式实现测量数据的封装和传输。针对空间环境的特殊性,分析空间力学环境、辐照环境对光纤传感测量系统的影响,研究了提高测量系统空间环境适应性的方法,为空间飞行器上的物理参数集成化测量提供一种有效的解决方案。The application of fiber sensing measurement for spacecraft is explored extensively to-wards the special requirement and limitation brought by the space environment. The fiber grating is select-ed from various techniques to transfer the physics such as temperature, pressure into signal. The design and realization of the demodulation for the fiber grating sensing system are analyzed comprehensively. CCSDS recommendations are applied to package and transmit the measuring data. Methods are explored aiming to improve the environmental suitability of the measuring system towards the special requirement of the mechanical and radiation environment. A feasible solution for the measurement of space physical pa-rameter is promoted.
