Document Type and Number:
Japanese Patent JP7256166
Kind Code:
B2
Abstract:
To provide a method for accurately observing a metallic system coating surface by visual inspection.SOLUTION: A method is performed by including: a linear polarization light source 10 for irradiating a metallic system coating surface S; and a polarization goggle 20 to be mounted by an observer. The observer observes, by visual inspection, the metallic system coating surface S at an angle obtained by allowing an angle formed between a polarization direction of irradiation light from the light source 10 and a polarization direction of the polarization goggle 20 to be greater than a zero degree.SELECTED DRAWING: Figure 5
