【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。
[Abstract]:In high resolution optical system, the primary aberration characteristic of optical system caused by eccentricity of optical element has become a factor that must be considered in system design and installation. Based on the analysis of the influence of lens transverse misalignment on aberration, In this paper, a method of adjusting and correcting optical parts considering aberration characteristics is proposed. Considering the effect of optical element eccentricity on aberration, the variation of pupil center position and image plane center position with the degree of lens eccentricity is derived, and the mathematical relationship between the correction of misalignment and aberration increment of optical system is established. In this paper, a transmissive optical system transverse offset correction method based on aberration theory is proposed, which can make up for the deficiency of existing Gao Si optical correction methods. Taking the three-lens collimation system as an example, the effectiveness of the proposed method is verified by ZEMAX software simulation. The experimental results show that the adjustment scheme selected by this method causes the smallest aberration increment in all the adjustment schemes. The effect of correction on the imaging quality of optical system is reduced.
