摘要

探索了智能手机在大学物理实验中的两个应用，即演示拍现象和演示人眼的三维视觉原理。在智能手机上安装频率发生器 APP，使手机同时输出两个频率接近的简谐声波，可以听到声音时大时小的声音上的拍现象; 测量了拍频，证实了拍频等于两简谐振动的频率之差。用智能手机首先拍摄一张照片，然后平移 6．0 cm，即大约人的两个瞳孔的距离，再拍摄一张照片; 将这两张照片同时显示在智能手机上，将手机放入 VＲ眼镜，可以通过 VＲ眼镜观察到三维的图像，演示了人眼的三维视觉原理。

Abstract:

Two applications of the smartphone in college physics experiment，i． e．，demonstrating beat phenomena and demonstrating three-dimensional vision of human eye，were explored．The frequency generator app was installed on a smart phone to make the phone output two simple harmonic sound waves with close frequency at the same time，and the beat phenomenon in sound could be heard． The beat frequency was measured and it was confirmed that the beat frequency is equal to the difference between the frequencies of two simple harmonic vibrations．A picture was taken using a smartphone．Another picture was taken after moving the smartphone 6．0 cm，i．e．，about the distance of two pupils of human eyes．These two pictures were shown on the smartphone at the same time．Then the smartphone was put in a VＲ glasses，and three-dimensional image was observed by the VＲ glasses．Three-dimensional vision of human eye was demonstrated by this means．

Key words: smartphone beat phenomena three-dimensional vision
