ABSTRACT:Due to the fiber optic sensor which compare with other sensor has a unique advantage，in recent years，optical fiber sensor and measuring technology become a new development direction in the field of instrumentation. Fiber optic temperature sensor has small volume， light weight，high sensitivity，less consumption，not affected by the interference of electromagnetic field，good insulation quality and great value of development.This topic is the design and construction of a new kind of optical F-P temperature sensor.

　　　Firstly，this article elaborated the advantages of the F-P senor and the principle of measurement of the temperature sensor.Then combine with the principle of optical F-P temperature sensor，illustrate the choice of optical  F-P temperature sensor materials concretely and shows the manufacturing operation of senor. Then the method is deduced cavity length with a function of temperature change.Then,analyse demodulation principle of F-P sensor simply.And use the demodulation principle of optical F-P sensor setting the the initial length of cavity of  F-P sensor.

Keywords:  temperature sensor；optical fiber； principle of measurement； F-P cavity length
