激光干涉测量较小位移的实验研究

STUDY ON EXPERIMENT OF MEASURING SMALLER POSITION SHIFT BY LASER INTERFERENCE

应用迈克耳逊干涉仪原理，采用光电转换技术及条纹计数技术．实现了对较小位移的测量，结果表明，在一定的测量范围内，大大地提高了测量的精度．

Based on Michelson Interferometer Theory, by photoelectric transformation technology and fringe count, smaller position shift measuring is performed. As a result,accuracy ration is greatly improved to a certain extent.
