【摘要】 本文介绍白光散斑法的基本原理以及用此法测量面内静态和瞬态位移的方法。文中采用白光进行散斑图的信息处理,全场等位移线为彩色条纹,易于判别条纹级次,这样就提高了测量的灵敏度。更多还原

【Abstract】 In this paper,the basic principle and experimental metlod of measuring instantaneous deformation by white light speckle method is discussed.Information of specklegrams is processed by white light. Displacement ccntcurs in whole field are shown by colour fringes,which are easy to identify,and thus the sensitivity of the measurement is improved.更多还原
