<p>A method of determining the thickness and/or the homogeneity of a moving linear textile formation in which the linear textile formation moves in a radiation flux (4) between a radiation source (5) and a CCD sensor (61) of radiation sensing the image of the moving linear textile formation by evaluating the irradiance of each element (611) of the CCD sensor (61) whereupon the real thickness of the linear textile formation is determined on the basis of the number of the shadowed elements, while monitoring the irradiance degree of at least one of the elements (611) subject to radiation of the CCD sensor (61), comparing it with a preset value of radiation received, determining and evaluating the irradiation values of the elements (611) subject to radiation of the CCD sensor (61) and using the irradiation values thus found for controlling the amount of radiation emitted by the source (5) of radiation so as to ensure a constant irradiation degree of the elements (611) subject to radiation of the CCD sensor (61) during the operation.</p> |
