Fiber Optic Sensors its small size, light weight, high sensitivity, less susceptible to electromagnetic interference and other advantages, humans developed various types of fiber optic sensors, gradually replaced the traditional sensors in human life.This paper describes the three characteristics of the fiber of their characteristics, working principle of fiber sensor and its classification in different ways. Focuses on the characteristics of the fiber optic temperature sensor, and temperature characteristics and properties of the principle of distributed optical fiber temperature sensors, fiber optic fluorescence temperature sensors, fiber grating temperature sensor, interferometric temperature sensor, and the use of their works and the characteristics of the fiber optic temperature sensors to the medical, construction, power systems, aerospace and other applications.The use of fiber optic temperature sensor works, based Mach - Ze Deer interferometer temperature experiments. And give advantages and disadvantages of fiber optic temperature sensor according to the temperature of the temperature experiment, and suggest improvements fiber optic temperature sensor temperature measurement method of his own views.
