Since the 90s of last century, fiber-optic sensing technology based on Bragg grating has received extensive attention from scientists, and has carried on a great deal of research.

Previously, the research team led by the associate professor of optical communication and optical network of the summer with cross-Gaussian filter method to achieve fiber-optic grating sensor demodulation, the results have been published in the Optics Letters journal.

Therefore, the research team in the near future work and further design of a narrow wavelength based on dual-wavelength high power laser pointer incidence of weak fiber grating sensing array demodulation method. At the input of the demodulation system, two laser beams having a certain central wavelength interval are used.
