Abstract:
Polarized light characteristics are detected and mapped to an application, such as product identification. A process of reflecting a directed light emission through a polarizing filter, and sensing the processed light emission having particular characteristics is provided. The characteristics of the sensed light emission is associated with a “color code” that is cross-referenced within a database of color codes.
