【摘要】 设计了一种新的干涉条纹计数仪 ,分析了对计数进行干扰的几种因素及排除的方法。该设计应用光电变换原理 ,把毛玻璃上的光信号转换成电信号 ,再经适当处理 ,把干涉条纹变化的数量用计数器记录并显示出来 ,比常规的干涉条纹计数手段更加自动化 ,数据更加准确直观更多还原

【Abstract】 A new interference fringe counter on the basis of photoelectric principles which converts optical signals on ground glass into electrical ones is introduced. Some interference elements of counting and the means to eliminate the interference are analyzed. After data processing and calculating, number of interference fringes is displayed by the counter. This meter is automatic and the data processed are more precise than those of the existing interference fringe counter.更多还原
