摘要
分析了衍射透镜的衍射效率及其对光学传递函数的影响，得出了总的光学传递函数和各衍射级次光学传递函数之间的加权和关系公式。最后进行了实例计算和讨论。
A weighted sum equation,which describes the relation between the diffractive efficiency and modulation transfer function of diffractive lenses,is derived.According to diffractive efficiency and optical transfer function,the total optical transfer function can be expressed with weighted sum of the series of order optical transfer functions of diffractive lights.The weighted factors are the diffractive efficiency.We employed the results to calculate MTF of various diffractive lens singlets and got consistent results with the literature .
