What are the functions of a fiber optic grating demodulator
The core work of demodulation for fiber optic grating sensing signals is to read and transform the return values of different center wavelengths of the fiber optic grating, and then obtain the changes in external information. Fiber Bragg Grating, as an intelligent sensor, has the advantages of small size, light weight, corrosion resistance, strong resistance. A demodulation algorithm is vital for a fiber Bragg grating (FBG) sensing system. In aircraft engine applications there is a need to measure dynamic signals such as variable pressures. used to support impact and ballistics explores testing the ext of generation a the limits of speed upwards of 3Mhz.
