【摘要】 设计了一种基于单片机的迈克耳孙干涉条纹计数电路,该电路具有清零和选择明、暗条纹计数的功能,能对"冒出"或"缩进"的干涉条纹进行自动计数,结构简单、操作灵活、成本低,应用于迈克耳孙干涉仪测波长实验,测量波长误差在3%以内。更多还原

【Abstract】 An interference fringes counter electric circuit is designed.The circuit is of simple structure,flexible operation and low cost.It can be applied in measuring wavelength by Michelson Interferometer,i.e.,Michelson interference fringe counter.This counter can clearly recognize bright and dark stripes.It can automatically count the "out" or "indented" interference fringes.Experimental verification of the wavelength error is within 3%.更多还原
