Abstract
The article describes the theory, characters and performance of the linear array of photodetectors includes CCD, PDA, CMOS and InGaAs, presents fiber grating sensor demodulation technique using linear InGaAs array and designs the demodulation system based on this technique. Furthermore, the system is used to measure the strain and temperature respectively, and prove the system have a good practicability. The demodulation system has a high resolution and measurement precision, changes the size of traditional Fiber Grating Sensors demodulation system essentially, and realizes basically the intelligence of the FBG sensors and lays a foundation for the industrialization of the FBG sensors.
