Abstract

PURPOSE:To prevent misinspection with a more exact color resolution by evenly diffusing the reflection of a spot light with a dome-shaped integrating ball arranged on an object to be inspected. CONSTITUTION:A spot light from a white light source 1 is projected on a scan mirror 4 and the reflected light is irradiated at the right angle to an object 2 to be inspected through a slit 10 of a semi-cylindrical dome-shaped integrating ball 9. The reflected light from the surface of the object 2 being inspected is scattered on the inner surface of the integrating ball 9 and diffused evenly. The diffused light applied to R, G and B filters 6 by way of an optical fiber 5 and the integrating ball 3 to resolute color. The quantity of light is measured with a photomulstiplier 7 and the output of the measurement is converted photoelectically. This enables the color resolution of even the object to be inspected regardless of irregularities of the surface.
