Title: Surface irregularity inspection method and device
Inventor: WASHISAKI ICHIRO
IPC: G01B11/30
Filed: 2000-06-07
Abstract: PROBLEM TO BE SOLVED: To detect irregularities on the surface of an object surely with a simple formation. SOLUTION: Illumination is executed on the surface of a test body 1 from a lattice-shaped illumination device 2 in the state where the border 6 between a bright part 4 and a dark part 5 is clear. A sensor 3 includes a movement- detecting solid-state image pick up device and picks up the periphery image of a part where the border 6 passes on the surface of the test body 1. If a irregularity defect 7 exists, brightness inversion parts 8, 9 are generated when the border 6 passes. The movement-detecting solid-state image pick up device in the sensor 3 picks up the images in each frame by pixels arranged matrically and detects the movement based on the difference of the images between the frames.  Since the brightness inversion parts 8, 9 are generated when the border 6 passes on the irregularity defect 7 on the surface of the test body 1, the irregularity defect 7 can be determined easily as the movement of the images.
