Abstract
Various approaches are described herein for enhancing biometric scanning in a biometric scanning system. For example, a porous region of a platen can be wetted with a liquid, the porous region sized and shaped for contact with skin of a subject (such as a finger or palm), and the porous region defining respective pore structures to house the liquid for wetting the skin when the skin is in contact with the porous region. Topological features of skin in contact with the porous region can be imaged, such as ridges of a fingerprint. The topological features generally contrast with a background field illuminated by a light source, with contrast enhanced in response to a presence of the liquid versus no liquid being present.
