摘要：

Roughness of a paper surface is particularly important in paper and board destined to be printed. Surfaces are often: coated and the amount of coating and method of application used depends on the roughness Of the base paper: WO present a Method to measure the roughness of paper based on the analysis of speckle contrast pattern on the surface: Images are captured by means of a simple configuration using a laser and a camera CCD. Then, We apply digital image processing, so this method can be considered as a non-contact surface profiling method that Can be used online.
