几何光学与波动光学的“无缝”对接——透镜等光程性的教学研究

Seamless Docking from Geometrical Optics to Waveform Optics——Studies on the Equal Optical Path of Thin Lens

通过薄凸透镜成像的高斯公式的推导,说明了薄透镜近轴成像时透镜的等光程性,从而将高中的几何光学和大学的波动光学进行了“无缝”对接.

Gaussian equations of thin convex lens in geometric optics are added because some physics textbooks for senior school students. Quantitative proof of the equal optical they are not listed in path of thin lens in waveform optics is presented when rays and points lie in the immediate neighborhood of the axis. Addition of Gaussian equations of thin convex lens in air is beneficial to the teaching and learning of waveform optics at university.
