A more comprehensive analysis of the characteristics of chirped Moire fiber grating. The development and application of chirped Moire fiber grating are introduced. Proposed the use of thin film transmission matrix to calculate the fiber grating, this algorithm will be regarded as a multi-layer grating superimposed on the film, the use of transfer matrix to calculate the grating characteristics, and this algorithm and other related algorithms were compared. As a kind of filter, the transmission characteristic of chirped Moire fiber grating is very important. Based on the length, chirp and phase shift of such fiber grating, the transmittance of grating is calculated and the result is optimized Analysis, come to the relationship between them
