  • Surface inspection apparatus and method
    Patent number: 6313913
    Abstract: A surface inspection apparatus is provided which uses at least two sets of surface inspection systems each comprising with a paired surface illumination device (A1, B1) and detection device (A2, B2), with each set of illumination devices and detection devices creating their own irradiation regions (51A, 51B) and detection regions (23A,23B), in which the irradiation and detection regions of one pair of illumination and detection devices does not over lap the illumination and detection regions of the adjacent pair of illumination and detection devices. The surface illumination devices preferably project light at an angle of 80° or more with respect to a normal to the surface being inspected (21). The detection devices detect light scattered by dust or defects on the surface to be inspected. The surface to be inspected can be moved in a direction perpendicular to the direction of the illumination and detection regions on the surface being inspected. Thus, the entire surface can be inspected.
