摘　　要：提出一种基于FBG（Fiber Bragg Gmting）光纤光栅传感器来实现温度、压力和加速度多参数同时测量的系统设计。采用在等强度悬臂梁上、下两表面对称放置两个FBG传感器，解决了加速度，温度和压力的相互影响问题：同时借镀层技术提高了FBG传感器的灵敏度。实验表明，三个参数能被精确、同时和实时测量，并且FBG传感器的灵敏度也提高了5～10倍。A multi-parameters simultaneous measurement system based on Fiber Bragg Grating （FBG） which can detect the temperature, the pressure and the acceleration was presented. Two FBG sensors were layed symmetrically in the two-side of the triangle cantilever beam. It solve the cross effect of acceleration, temperature and pressure. Besides, the material-coated technique was used to increase the sensitivity of FBG sensor. As indicated by the experiment, the three parameters can be measured in accuracy and real-time, and the FBG sensitivities can be increased 5-10 times.
