IPC: G01N21/90
Filed: 1987-11-16
Abstract: PURPOSE:To detect an abnormal shape by a method wherein lights are projected from a plurality of light sources onto a surface to be inspected, regular reflection lights thereof are received by a photoelectron conversion camera and waveform patterns of electric signals corresponding to separate light source images are observed. CONSTITUTION:In the case when a teardrop 202 is protuberant in the lip 201 of a glass, lights projected from light sources 203 and 204 to the lip 202 and reflected from a part of a normal shape proceed in parallel to the center line of the glass and are imaged and detected at definite positions by a camera lens 205. When the lights projected to the drop 202 are reflected by a surface inclined from the center line CL of the protuberant shape to the direction of the circumference of the glass, they are not parallel to the center line CL as shown by l and l' and do not enter the lens 205 in some cases, and there occurs a difference in an incident light according to the presence or absence of the drop 202. In this way, a scuff mark or an abnormality in the shape can be detected from variation in an incident light.
