摘　　要：由于自由曲面灵活的空间布局和设计自由度,使光学系统的结构得到了简化,像质得到了提高。本文通过设计实例详细介绍了在光学设计软件CODE V中运用用户自定义面型UDS(user defined surface)的功能和计算机动态链接库DLL(dynam ic link library)软件技术设计含有自由曲面光学系统的方法。通过利用此方法设计了球面和锥面光学系统,验证了其准确性和可靠性。并且利用此项技术设计了含有自由曲面的光学系统,使光学系统达到了质量轻、体积小的设计目标。此项技术扩充了CODE V软件的功能,有效地拓宽了CODE V计算复杂面型的能力。With the flexible spatial layout and the degree of design freedom of the free form surface （FFS）, the structure of the optical system was simplified and the quality of the image was improved. The method of using user defined surface （UDS） function in CODE V and computer dynamic link library （DLL） technique to design an optical system incorporating with FFS is introduced through a design example. The accuracy and reliability of the approach are verified by the design example of an optical system with spherical and conic surfaces designed by CODE V. An optical system with a FFS prism is also designed with the method, and it made the optical system light in weight and compact in size. The approach expands the functions of CODE V and effectively enlarges its capacity to calculate complicated surface.
