Research of a Micro-scale Measurement System Based on Michelson Interferometer

Lu Hong-fang,TAN Xiao-ping(School of Physics and Information Engineering,Jianghan University,Wuhan 430056,Hubei,China)  
A micro-scale measurement system based on Michelson interferometer is designed.The system can transform the micro scale of the measurement object into the change value of movable holophote,take use of photovoltaic cells to transform light signals into electrical signals.Through signal acquisition,the data were processed by microcontroller and the results were showed by liquid crystal display.The measurement results of standard feeler demonstrate that,the system has the properties of high accuracy,easy operation,fast measurement and so on.
