投影式水波演示仪的设计

Design of Projection-type Water Wave Demonstration Instrument

  • 摘要: 该文演示的实验仪器由振源振动模块、闪频光源模块、投影成像模块和总控电路等组成,振动源驱动振子在水槽中产生水面波,经LED光源照射及平面镜反射后,将波动图像投影于毛玻璃屏幕上。通过调节振动和光源闪烁的频率,波动图像可以出现不同的显示效果。更换不同种类的振子,并配合一些专用附件,可以演示圆形波、平面波,及波的反射、折射、干涉、衍射等波所特有的现象。

     

    Abstract: The demonstration instrument consists of vibration source module, stroboscopic module, projection module, and control circuits. The source drives oscillator to generate water wave in the flume. After LED irradiation and plane reflection, the wave image is projected on the ground glass. Different vibration frequency and flicker frequency produce different effects of the wave image. With different oscillators and some special modules, special wave images can be presented, such as circular wave, plane wave, reflection, diffraction and interference.
