Abstract
Provided herein is an apparatus including an imaging lens assembly configured to collect reflected light from a surface of an article; an image sensor configured to receive reflected light from the imaging lens assembly, wherein the imaging lens assembly and the image sensor are each arranged at different angles for focusing on substantially an entire surface of an article; and a processing means configured to process signals from the image sensor corresponding to polarized reflected light and subsequently generate one or more features maps.
