%X In the use of digital image correlation(DIC) technique for full-field deformation measurement,the tested object surface must be covered with a random gray speckle pattern,which deforms together with the object surface as a carrier of deformation information.However,in practical applications,the speckle patterns on tested surface may show distinctly different intensity distribution characteristics and have an important influence on DIC measurements.How to assess the overall quality of different speckle patte...
