摘　　要：提出一种改进的光纤法布里—珀罗(F-P)腔结构的热双金属片温度传感器。利用常见的法兰盘光纤连接器,以环状结构约束热双金属片的形变。给出环状约束具体有限元分析结果;环状约束可以简单改变环孔大小灵活适应不同量程的需要;实际制作了环状约束光纤热双金属片F-P腔温度传感器,进行了相关实际测试。A temperature sensor with circular confined thermal bimetal sheets, based on improved optical fiber Fabry-Perot（F-P） cavity is introduced. The scheme is based upon F-P interference,the F-P cavity is composed with one polished surface of bimetal and one polished end face of optical fiber inserted in a common flange optical fiber connector. The finite element snalysis（FEA） results for the ring confinements are given; the size of the ring hole can be simply changed to agilely meet the requirement of the different measurement range; the F-P temperature sensors with the developed bimetal sheets COnfinement mechanism are designed and fabricated, the practical measurements are carried out.
