IPC: G01N21/892
Filed: 1980-06-12
Abstract: PURPOSE:To enable a true defective part to be stably detected, by performing a defect detection  on the basis of the difference between the average value of the received scanning light measurement values corresponding to the surface conditions of two or more continuous parts and the  average value of the measured values of a plural parts, 10-100 times as many as the former. CONSTITUTION:The received scanning light measurement values, corresponding to the surface  conditions of a moving long and flat object, obtained by a light-receiving part 7, are applied to a defect detecting part 84. In a signal averaging part 14, the measured values of continuous six parts or the like corresponding to one turn or the like of a rotating mirror are averaged to be a value independent of mechanical noises or the like. On the other hand, the measured values of a plural  parts, 10-100 times as many as the former, are averaged in a signal averaging-standardizing part 15 to be a value changing slowly. When the difference between both the average values is calculated in a subtracting part 12, a value is obtained which corresponds to a true defective part including flaws, stain, thickness mottles and the like independently of the surface bending and the  like in traveling, and outputted through a defect decision part 10 in which a defect reference value  has been set. Accordingly a true defect can be stably detected.
