Experimental investigation of sensor for temperature compensation of fiber-optic gyroscope

The importance of temperature measurement in the experimentation for fiber-optic gyroscope(FOG) and the limitation of traditional temperature measurement are analyzed.A kind of circuitry of temperature sensor is designed,the work principle,excellence,the primary component performances and its functions are dissertated in detail.Experimentation shows that the circuitry of temperature sensor has good linearity,repeatability and the characteristic of real time,and it can be used to the experimentation of temperature compensation for FOG and the control systems for precision temperature.
