Measuring beam-expanding ratio based on position-shift method

GAO Hong-yun;LI Min;CHEN Qing-ming;YI Ying-yan;Department of Physics,School of Science,Wuhan University of Technology;  
Using the current equipment in laboratory,a measurement device of beam-expanding ratio was set up based on a position-shift method.The experimental results showed that the positionshift method could accurately and conveniently realize the measurement of beam-expanding ratio with the advantages of simple,low cost and high accuracy,the relative error was less than 1%.
