自动记录干涉条纹数目装置的研制

针对大学物理实验——迈克耳逊干涉仪的原理与使用实验中，实验观察人员记录大量干涉条纹数目过程中存在较大人为误差的实际状况，研制了一套能够自动记录条纹数目的实验装置，切实解决了实验过程中的人为误差问题，提高了实验的准确性。装置具有设计原理简单巧妙、使用方便、成本低廉的特点，有很好的推广前景。

Designation of the Educational Experiment Device to Automatic-Record the Amount of Interference Fringes

In college physics experiments Principles of Michelson Interferometer and Application, it need the experimenter to record the number of interference fringes by themselves, and the amount is 500 at least at once, so there are many errors easily. In order to improve the accurate of experiment and reduce the rate of operative error, one device of automatic recording the amount of interference fringes is designed. Particularly,this instrument with simple and well-designed principle,and easily to be operated,with inexpensive cost,has the very good promoted prospect.
