摘要：

In this study, the total deviation of central diffracted beams caused by the periodic projection effect and refraction of zero-order diffracted beam of diffractive optical element was theoretically investigated. The theoretical model of the relationship between the total deviation of central diffracted beams and the combining angle of the ith order incident beam was developed. Inversely, the total deviation of central diffracted beams can be used to calibrate the actual combining angle of the ith order incident beam, further guide the correction of the actual combining angle in coherent beam combining.
