Abstract RU 2018810 C1

FIELD: automatic inspection systems. SUBSTANCE: when the control bearing ball is illuminated with diffused light, the image formed by the light reflected from practically entire convex spherical surface of said ball shows any defect as a light-contrast picture against a virtually uniform background of diffused light which shows the defect-free part of the ball surface.
