摘要
本文从分析传统中心投影法入手，介绍了平面圆柱投影（ＦＣＰ）的基本概念、主要特点，深入地探讨了实现ＦＣＰ的一种光学器件——全景环形透镜（ＰＡＬ）的工作原理。ＰＡＬ具有线性投影关系、方向选择性、景深无限远等重要特性。优化设计了一个口径为３４ｍｍ的ＰＡＬ，模拟计算进一步证实了ＰＡＬ的上述特性。
: Beginning with analysis of traditional central perspective, this paper introduces the basic concept of flat cylinder perspective (FCP) and profoundly discusses the working principles of panoramic annular lens (PAL), one of the optical elements that can realize FCP. PAL has many important characteristics such as linear perspective, direction selection and infinite depth of field. A PAL with diameter of 34mm is designed through optimizing. Simulating calculation strongly proves the characteristics mentioned above.
