光学技术在我们日常生活的许多方面都可以找到。我们已经开发了三个实验,使用玩具盒中或房子周围的物品来演示和解释光学概念。这些实验的视频、原理和应用程序可以在我们的YouTube频道上找到。第一个实验用模塑油灰制成可变形透镜,用光导分别观察折射和全内反射。油灰的特性允许手动模塑成不同的形状,以实时观察光在油灰中的传播情况。第二个实验是了解颜色的吸收和反射。衣服的颜色图案会根据用来照亮它的光的颜色而变化。该实验说明了光通信如何使用不同的颜色来支持多个用户。第三个实验使用气泡来说明光干涉,这是眼镜镀膜背后的原理。由于光干涉,气泡上的不同位置可以看到不同的颜色。上述实验可以通过我们的外展计划在家里或学校进行。在我们的学校外展期间,我们将上述动手实验与两个演示联系起来。第一个演示是一个激光传输的音频系统,它解释了如何使用光纤传输电信号。而第二个允许观察激光如何在光纤内被引导。基于玩具的实验是向学生介绍复杂概念的一种有趣的方法。
Optical technologies can be found in many aspects of our daily lives. We have developed three experiments using items that can be found in a toy box or around the house to demonstrate and explain optical concepts. Videos of the experiments, their principle, and applications are available on our YouTube channel. The first experiment uses moldable putty to make a shapeable lens and light guide to observe refraction and total internal reflection respectively. The putty’s characteristics allows for hand molding into different shapes to observe how light propagation is changed within the putty in real time. The second experiment is to learn about color absorption and reflection. The color pattern of clothing would change depending on the color of light that is used to illuminate it. The experiment illustrates how optical communication can use different colors to support multiple users. The third experiment uses a bubble to illustrate light interference, the principle behind eyeglasses coating. Different colors are seen at different locations on the bubble due to light interference. The above experiments can be carried out at home or at school through our outreach program. During our school outreach, we relate the above hands-on experiments with two demonstrations. The first demonstration is a laser-transmitted audio system that explains how electrical signals can be transmitted using optical fibers. While the second allows for the observation of how laser light is guided within an optical fiber. The toy-based experiments are a fun approach to introduce complex concepts to students.
