摘要
本文设计自制了便携式波动光学演示仪.该演示仪采用红、绿双色半导体激光器作为光源,配备多种规格的干涉、衍射和偏振组件,可以演示杨氏双缝干涉、多缝干涉、单缝衍射、小孔衍射、一维和二维光栅衍射、偏振等波动光学的主要内容.仪器体积小巧,激光功率大,采用电池供电,这些优点使之便于携带,无需暗室而可在普通教室演示,双色平行光源可以同步对比不同波长的干涉、衍射效果,实现了波动光学理论内容与实验现象的同步课堂演示.
This article introduced a self-made portable demo-set of wave-optic. The set can demonstrate a majority of experiments on simultaneous comparison of dual wavelength in the wave-optics, such as Young's dual-slit interference, multi-slit interference, single-slit diffraction, pinhole-diffraction, grating diffraction, through the red and green parallel laser as light source. The size of the set is small with high powered laser and battery power, which is very convenient to carry. It can be used in the ordinary classroom instead of the darkroom. The dual wavelength parallel light source can compare different wave length interference and diffraction effect, and lead to the simultaneous class demonstration on wave-optics theory and the experimental subject.
