文中计数器主要由信号接收、信号调理放大、模数转换、信号处理及计数显示几部分组成,其中信号处理以Atmel 89C52为中央处理器,信号接收所用的传感器由光电二极管阵列构成,对激光波段敏感并且能够有效抑制紫外和红外波长的光,信号放大器采用直流模拟调制技术,避免了大多数隔离放大器模块所存在的电磁干扰问题。实验证明,该计数器操作简单,缩短了测量时间,提高了计数精度。

关键词: 干涉条纹, 计数器, 激光, 迈克耳逊干涉


The counter is mainly consisted of the signal reception,signal conditioning,amplification,analogtodigital conversion,signal processing and count showAtmel 89C51 is responsible for signal processingOptical signals from laser is received by the sensor consisted of photodiode array,and the sensors is sensitive to laser band and can inhibit ultraviolet and infrared wavelengths of light effectivelyAmplifier modulation adopts DC analog signal technique which can avoid the electromagnetic interference that most of the isolation amplifier module haveExperimental results show that the counter is operated simply and it can shorten the measurement time and improve the accuracy of the count

Key words: interference fringes;counters;laser;Michelson interferometer
