Таким образом, предлагаемый способсуд т о дефекте, отличающийс тем, позвол ет определить характер развиваю-что, с целью определени характера развищихс дефектов в листовых издели х и по- 5ти дефекта и повышени точности контровысить точность контрол за счет уменьще-л , предварительно определ ют основные ни вли ни на результаты контрол местапервые две составл ющи.е спектра нормальрасположени дефекта и характера его раз-ных мод, принимают сигналы этих мод, а о вити .дефекте суд т по результатам сравнени Thus, the proposed method of defect, which differs in that, allows one to determine the nature of the develop- ing, in order to determine the nature of the developing defects in sheet products and a 5-fold defect and to improve the accuracy of the contrast, the control accuracy is reduced by The main effects on the results of monitoring the location of the first two components of the spectrum of the normal position of the defect and the nature of its different modes receive signals from these modes, and the defect is judged by the results of the comparison.
