Abstract
A retrographic sensor includes a transparent structure, a transparent elastomeric pad, and an at least partially reflective layer. One or more excitation light sources emit light toward a side surface of the transparent structure. The side surface may include a fluorescent layer, where the light from the one or more excitation light sources excites fluorescent emissions from the fluorescent layer. The fluorescent emissions may illuminate the at least partially reflective layer.
