Case number: #21868
A retrographic sensor includes a transparent structure, a transparent elastomeric pad, and an at least partially reflective layer. One or more light sources emit light into a side surface of the transparent structure. The light undergoes internal reflection in the transparent structure and is reflected toward a camera oriented toward the transparent structure. The at least partially reflective layer may be semi-specular in some embodiments.
