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。
In the high resolution optical system, the primary aberration of the optical system caused by the eccentricity of the optical element has become a factor that must be considered in the system design and setup. Based on the analysis of the influence of the lens lateral offset on the aberration, Optical Component Adjustment and Adjustment Method Considering the Influence of Aberration Characteristics. Considering the influence of eccentricity of the optical element on the aberration, the change of the center of the pupil and the center of the image plane with the eccentricity of the lens is deduced. The mathematical relationship between the amount of the optical system offset correction and the aberration increment is established, A transverse aberration correction method based on the aberration theory of transmissive optical system is proposed, which can make up for the deficiency of the existing Gauss optical correction method. Taking the three-lens collimation system as an example, the validity of the proposed method is verified by ZEMAX software simulation. Experiments show that the adjustment scheme chosen by this method has the least increment of aberration in all adjustment schemes, Impact of system imaging quality.
