摘　　要：根据费马原理,采用逐个曲面成像法,推导出处于任意介质情况下薄透镜和厚透镜的成像规律,分析所得的主点和光焦度,结果显示:对于不同起点下的物距、像距,成像规律形式不同,以主点情况下为简;除空气中的薄透镜,光焦度并不完全由2个折射曲面的光焦度决定.According to Fermat Principle,by analyzing consecutive curves,we can derive the imaging principles of thick and thin lenses in any type of transmission media.Results show that the obtained corresponding principal points and focal power vary in different object distance,image distance and imaging principle,where it is simple under the circumstance of principle point.Except for a thin lens in the air,the comprehensive focal power is not completely determined by the focal power of two individual curves.

关 键 词：透镜 成像规律 主点 光焦度
