Slide 2

In layman's terms it is an instrument that measures gloss. By reflecting a light source off of a glossy object twice, second time through a polarizing lens, it is possible to measure the intensity of the light.

Slide 3

Gloss is used as a criterion in industries to evaluate the quality of a product Human evaluation = subjective w/ many sources of error Solution-- automated device to remove human element and provide results that are: Objective Accurate Consistent

Slide 4

RIT Imaging Science Dept. had experimental technology to obtain quantitative measurements of gloss Cumbersome; not user-friendly Needed a way to commercialize the process In April 2008, a senior design team started a prototype that was user-friendly, robust, compact, automated, and reliable Device was half-completed we picked up where they left off
