The word "gloss" is intuitively easy to understand, but making an optical measurement that correlates well with the perception of gloss remains a challenge. The hypothesis behind this project is that both spatial resolution (micro-) and angular resolution (gonio-) are required of an instrument in order to correlate meaningfully with visual perceptions of gloss and also with the underlying causes of gloss. Thus, a micro-goniophotometric bench-top instrument has been developed and demonstrated. This instrument collects polarized and un-polarized reflections from a sample wrapped around a cylinder to extract the specular and diffuse components. While this instrument has been successful in collecting more information than a traditional gloss meter, there are two issues that prevent its mass adoption: the above instrument is a bench-top experimental device that is not user-friendly and work is needed to correlate the device output to human visual perception. The objective of this multidisciplinary design project is to address the former issue. Correlation of the device to human visual is more appropriate as a research topic.
