Abstract
An optical dispersion finger sensor includes an integrated circuit substrate, and an optical source for directing light into a user's finger when positioned adjacent the integrated circuit substrate. The light may propagate into and be dispersed by the user's finger so that at least a portion of the dispersed light exits the user's finger in a direction toward the integrated circuit substrate. The sensor may also include at least one optical dispersion sensing pixel on the integrated circuit substrate for sensing dispersed light from the user's finger. A processor may be connected to the optical dispersion sensing pixels for generating optical dispersion biometric data based upon dispersed light from the user's finger.
