在讲授“几何光学”这门课时,为了使学生尽可能直观地看到各种光学现象,我们研制了一台激光光学演示仪,作为形象教学的教具,其外形如图1所示,它由激光电源、演示箱、烟雾盒三部分组成。演示箱是进行光学演示和实验的空间,其中可装有各种演示用的光学零件,为了使激光光线更明显地显示出来,设有烟雾盒,以造成演示箱内烟雾。使激光光线在烟雾中产生散射,这样就可显示出鲜红明亮的激光光线。
In teaching “Geometry Optics” this class, in order to make students as intuitive as possible to see a variety of optical phenomena, we developed a laser optical demonstrator, as a teaching aids, its appearance as shown in Figure 1, which consists of Laser power, demo box, smoke box composed of three parts. The demo box is a room for optical demonstrations and experiments where various optical parts for demonstration purposes can be installed. In order to make the laser light appear more clearly, a smoke box is provided to cause smoke in the demonstration box. So that the laser light scattering in the smoke, so that you can show bright red laser light.
