Title: Method and device for inspecting outward appearance
Inventor: FUJIMOTO YASUKAZU
IPC: G01N21/952
Filed: 1983-09-30
Abstract: PURPOSE:To eliminate an error in decision making due to a cutting chip which sticks to a surface to be inspected by arranging auxiliary optical systems on the left and right sides of a plane containing a projection and a photodetection system, and deciding on the ruggedness state on the surface to be inspected from the difference in the time of variation in the amount of photodetection between two auxiliary optical systems while deciding on whether abnormal reflection is caused on the surface to be inspected from the amount of photodetection of a photodetection system. CONSTITUTION:The 1st and the 2nd auxiliary photodetection systems 14 and 15 are arranged separately on the left and right sides of the plane containing the projection and photodetection systems 12 and 13, and the ruggedness state on the surface S to be inspected is discriminated from the difference in the time of variation in the amount of photodetection between the two auxiliary photodetection systems 14 and 15 whereas a decision on whether abnormal reflection is caused by the surface S to be inspected is from the amount of photodetection of the photodetection system 13. Consequently, it is decided that the inspected surface S is an abnormal reflecting surface when the quantity of light reflected toward the plane containing the auxiliary photodetection systems 14 and 15 increases while the quantity of light reflected in the normal reflection direction decreases.
