几种理想光组作图法成像实例分析

Example Analysis on Several Ideal Optical Group Mapping Methods

'应用光学'是光电信息等专业的基础课程,而理想光学系统是该课程的重要内容,目的是帮助学生建立基点的概念,在掌握理想光组等效光路模型的基础上,培养学生运用作图法求解像的大小、位置及正倒虚实.本文通过几个实例,探讨了不同形式的理想光组作图法成像的作图要领,相关分析对应用光学理想光学系统内容的教学具有一定的启发意义.

Applied optics is one of basic courses for Optoelectronic Information Program and so on,and ideal optical system plays an important role in this course.The purpose of this course is to help students establishing the concept of main point,obtaining images by ray tracing based on the equivalent models.In this paper,through several examples,we discuss how to determine graphically the location and size of the image.The related discussions will be helpful for lecturing this part of the course.
