Zusammenfassung:	System and procedure for measuring the roughness of a paper sample by analyzing the texture pattern of the speckle. System for measuring the roughness of a sample (2) of paper, which with a laser (1) and a beam expander (11) at an angle and distance determined with respect to the sample (3), a digital camera (3) in the direction normal to the sample (2), a processing device (4) with an adapter, and with at least one power supply. Method for measuring the roughness of a sample (2) of paper, comprising the following steps (a) a laser beam is projected and expanded on a sample (3) (b) a camera (3) captures the image, obtaining a speckle pattern (c) the camera (3) sends said speckle pattern to the processing device (4) (d) the processing device (4) obtains the roughness parameter of the sample (2) through a descriptor of the co-occurrence matrix of gray levels.
