Base on this expression, the spectra in the diffractionfield were investigated theoretically.
根据该表达式对衍射场中的光谱进行了理论研究。

By solving these equations, the diffraction trace of a curved surface and the position of the edge's diffraction point are determined so that the diffractionfield can be obtained.
求解寻迹方程,便得到曲面绕射线的轨迹和边缘绕射点的位置,从而可以计算它的绕射场。

Another important application of diffraction theory is the study of the far field divergence Angle of a collimated light beam.
