Abstract:The article describes the theory, characters and performance of the linear CCD, CMOS and In- GaAs imaging sensors, presents the technique of demodulation for FBG based on the linear InGaAs imaging sensor, and designs the demodulation system based on the linear InGaAs imaging sensor. Furthermore, we control the system through the computer to measure the strain and temperature respectively, and attain a good result. The demodulation system has a high resolution and measurement precision, realizes basically the intelligence of the FBG sensorsand lays a foundation for the industrialization of the FBG sensors.
Keywords:InGaAs  imaging sensor  FBG sensing  demodulation system
