折射率跃变的一般光学界面上光折射的代数关系

Algebra equation for light refraction in general optical curved faces with mutation refractivity in two sides

根据几何光学中的光线方程,推导出了折射率跃变界面处光折射的代数方程,依据该方程讨论了球面界面的"焦点"、"焦距"问题并用计算机进行了模拟.该方法对学生理解光的传播行为及提高几何光学的教学效果有帮助.

The algebra equations for light refraction in general curved faces with mutation refractivity in two sides are given based on the light-ray equation of geometrical optics. The problems about focus and focal length of spheric faces are discussed and simulated with computer. This method is helpful for teaching and comprehending the light behavior in geometrical optics.
