【摘要】 基于Arduino单片机实现迈克尔逊干涉仪自动测量,采用Arduino单片机控制整个设备,通过光敏模块读取数据并将数据反馈单片机进行处理。考虑到微小震动对迈克尔逊干涉仪会产生巨大的影响,采用一种识别光信号稳态的智能程序,消除了信号中本底数据的振荡。以测量He-Ne激光波长为例,直观揭示该方案不仅实现了实验的自动化,使实验精度得到大幅提高,而且具有较好的移植性和可开发性。更多还原

【Abstract】 Michelson interferometer is a precise instrument which focuses on fine distance measurement. Recently,improving its accuracy and automation is of great significance. The project, automatic measurement applying on Michelson interferometer based on Arduino singlechip,can solve this problem. In this project,Arduino singlechip controls the whole equipment. The device reads data using photosensitive module,and sends the data back to the singlechip. Considering the great affect from the tiny vibration of the whole equipment,we design an intelligent program which can identify the steady state of optical signal. Besides automatic and a substantial increasing of experimental accuracy,the project offers portability and exploitability.更多还原
