摘　　要：在高分辨力光学系统中,光学元件偏心引起的光学系统初级像差特性已经成为系统设计和装调必须要考虑的因素,文中拟从分析透镜横向失调量对像差影响的基础上,提出了一种考虑像差特性影响的光学零件装调校正方法。在考虑光学元件偏心对像差的影响的情况下,推导了光瞳中心位置和像面中心位置随透镜偏心程度的变化,建立了光学系统失调校正量和像差增量之间的数学关系,提出了一种基于像差理论的透射式光学系统横向失调校正方法,可以弥补现有高斯光学校正方法的不足。以三透镜准直系统为例,利用ZEMAX软件仿真验证了文中方法的有效性,实验表明该方法所选择的调整方案在所有调整方案中引起的像差增量最小,降低了校正过程中对光学系统成像质量的影响。Based on the consideration of the influences of decenter element to aberration, the positions of pupil center and image center as functions of lens decenter was derived and the relationships of adjustment and aberration increment was established. Then, the calibration method on lateral displacement transmission-type system based on aberration theory was advanced, which cover the shortages of calibration method based on Gauss optics. An example was also set up to prove the effectivity of this method. The result showed that the adjust programme chose by this method caused the minimum aberration increment which reduced the influence to the imaging quality. This theory could be used to instruct the calibration on misalignment system.
