摘要
王之江教授在《光学设计理论基础》一书中提出:用光瞳坐标和物面坐标的变化来定量计算偏心所引起的初级波差的变化.本文在此基础上导出了中心偏差所引起的轴上点弧矢方向MTF 下降值的近似算式;并对两个照相物镜进行了计算,实际计算表明,在波差增量和空间频率不大时,近似计算的结果是满意的.最后对该式进行了讨论,从中得到了两个有实有价值的结论.
“The Principles of Optical Design”written by prof.Wang Zhijiang (?)rese(?)s (?)the variation of primary wave-aberration caused by the eccentricity error of optical(?) elements can be calculated quantitatively by the variation of the coordinates of pupilplane and object plane.Based on this theory,an approximat formula for the sagittalMTF decrease caused by the eccentricity error of optical elements for the point on-ax-is is introduced.When the formula is used for calculating two photogarphicobjectives,the result shows that the calculation will be satisfactory if the increase ofwave-aberration and the spatial frequency are small.This paper also discusses theformula and draws two conclusions of practical use.
