Tolerance analysis and tolerance sensitivity optimization (desensitization) are important and necessary for manufacturability. However, compared to the optimization of optical performance, tolerance analysis is still time-consuming. A machine learning approach for the fast robustness estimation of lens systems is proposed. The results of the machine learning estimation and the other four different methods are compared with the results of the Monte Carlo analysis. The proposed model is added to the merit function in commercial software for optimization to reduce the sensitivity.
公差分析和公差灵敏度优化(脱敏)是可制造性的重要和必要条件。然而,与光学性能的优化相比,公差分析仍然是耗时的。提出了一种用于镜头系统鲁棒性快速估计的机器学习方法。将机器学习估计和其他四种不同方法的结果与蒙特卡罗分析的结果进行了比较。将该模型加入到商业软件的优点函数中进行优化,以降低灵敏度。

Merit figures for fast estimating tolerance sensitivity in lens systems 快速估计透镜系统公差灵敏度的优点
Pub Date : 2010-09-09 DOI: 10.1117/12.868874
Lirong Wang, J. Sasián
We propose two parameters CS and AS for fast estimating sensitivities to constant coma and linear astigmatism in a misaligned lens system. We show that these figures correlate well with actual tolerancing of some lens systems.

A custom optical microscope with an integrated liquid lens to enable an extended depth imaging in biological tissue has been fabricated and shown to provide subcellular resolution using Gabor image fusion in an optical coherence tomography setup. In this paper, we report on the development and assessment path of this technology over the last few years. Specifically, we report on the optical design as well as the MTF prediction and experimental measurements of the new optical microscope head. The microscope head was integrated in a custom optical coherence microscopy setup that is presented. Images of an African frog tadpole, ex vivo human breast excised tissue, and in vivo skin images, acquired with the integrated instrument, are presented.

Lens design with suppressed first order reflections 抑制一阶反射的透镜设计
Pub Date : 2010-07-01 DOI: 10.1117/12.868917
J. Buchheister, C. Weth
Optical systems with a reflected light condition, e.g. microscopes with reflected light illumination or fundus cameras, need to have weak first order ghosts or even to be completely free from them. Sequential ray tracing can be used to control optical performance and reflections on a ray basis during optimization. This is significantly more efficient in computation time and convergence than the usual approaches with non-sequential ray tracing or reconfigured optical systems to cover all critical ghosts. An ophthalmic lens for a fundus camera was designed with first order reflections stripped out by applying sequential ray tracing. The merit-function only had to be completed under certain conditions guaranteeing the absence of any reflections. No additional reconfiguration of the optical system in the design software was necessary.
具有反射光条件的光学系统,例如具有反射光照明的显微镜或眼底相机,需要具有弱的一阶鬼影,甚至完全没有它们。在优化过程中,顺序光线跟踪可用于控制光性能和基于光线的反射。这在计算时间和收敛性方面比通常使用非顺序光线跟踪或重新配置光学系统以覆盖所有关键幽灵的方法要有效得多。采用顺序光线追踪的方法,设计了一种滤除一阶反射的眼底相机镜片。只有在保证没有任何反射的某些条件下才能完成功绩函数。不需要在设计软件中对光学系统进行额外的重新配置。
