自由曲面光学虚拟制造与检测系统的探讨

自由曲面光学产品设计、制造与检测的工艺流程，通常采取试凑法逐次逼近。由于加工 检测 再加工，循环往复，既费时，成本又高，产生了瓶颈问题。为了解决此弊端，本文运用虚拟制造技术，提出光学虚拟制造的基本构想，即虚拟制造系统结构模型，给出光学系统虚拟原型的构成和光学系统成像质量虚拟检测系统的构成，讨论光学成像质量的仿真检测以及敏度分析方法。研究结果表明：运用虚拟制造与检测技术，可缩短研发周期，降低成本，优化工艺并提高产品质量。

Investigation into virtual manufacturing procedure for freeform optics

Successive approximation method is adopted in the design,manufacture,and test of freeform optics.This approach requires repeated trial-and-error processes before a satisfactory result is achieved.Such repetitions are not only expensive,but also time consuming,and it becomes a bottle-neck in the overall process flow.The virtual technology is an effective and fast way to solve this problem.An investigation into a virtual manufacturing and testing procedure(VMTP) for freeform optics is presented in this paper. The essential concepts about VMTP for optics ultra-precision machining(UPM) are put forward,including the construction of a VMTP model,the prototype structure of an optical system,and the virtual testing and sensitivity analysis of the imaging quality.The investigation indicates that this approach can accelerate the R&D process,reduce the cost,enhance the manufacturability and improve the product quality.
