Abstract
A diffractive-optical-element-based glossmeter (DOG) is used for optical inspection of local gloss variation of planar ABS-PC plastic samples possessing different surface roughness. The DOG was utilized to detect gloss differences, which were measured at successive microscopic areas by scanning a macroscopic surface area. The gloss variation is presented as a 2-D map of gloss measurements. It is suggested that DOG can provide a robust glossmeter for industrial use. © 2003 Society of Photo-Optical Instrumentation Engineers.Keywords
