摘要:
设计了一种能自动适应不同背景光强的新型迈克尔逊干涉仪条纹计数器.利用光敏二极管将条纹的变化转化为电信号并与数控分压电路的输出进行差动放大,经施密特触发器整形后,送入单片机计数并显示.实验证明,本计数器可以适应不同的背景光强和光源光强,具有精确度高、操作简便、适应性强等优点.
Abstract:
A novel Michelson interferometer fringe counter that can automatically adapt to different background light intensities is designed. The photodiode is used to convert the change of fringes into electrical signals and differential amplification with the output of the numerical control voltage divider circuit, and after being shaped by Schmitt trigger, it is sent to the single-chip microcomputer for counting and display. Experiments show that this counter can adapt to different background light intensity and light source light intensity, and has the advantages of high accuracy, easy operation and strong adaptability.
