In view of the limitations of the current methods of grating spectral multiplexing and demodulation,aiming at improving the precision of grating spectral multiplexing and demodulation,a method of grating spectral multiplexing and demodulation based on artificial intelligence technology is proposed. Firstly,the principle of grating spectral multiplexing and demodulation is analysed,and the essential factors affecting the effect of grating spectral multiplexing and demodulation are found.Then,the signal of grating spectral multiplexing and demodulation is collected,and the model of grating spectral multiplexing and demodulation is established by using artificial intelligence technology,and the experiment of grating spectral multiplexing and demodulation is compared with other methods. The experimental results show that compared with the existing methods,the demodulation time of this method is shorter,only 0. 29 s,and its demodulation accuracy can reach 92%. It shows that this method has the advantages of high precision and fast speed and can effectively complete the multiplexing and demodulation of the grating spectrum.
