Finger sensor using optical dispersion sensing and associated methods
First Claim
1. An optical dispersion finger sensor apparatus comprising:
- an integrated circuit substrate comprising a semiconductor material and having an upper surface;
an optical source integrated on the upper surface of said integrated circuit substrate for directing light into a user'"'"'s finger when positioned adjacent said integrated circuit substrate, the light propagating into and being 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 said integrated circuit substrate;
at least one optical dispersion sensing pixel integrated on the upper surface of said integrated circuit substrate for sensing dispersed light from the user'"'"'s finger; and
a processor connected to said at least one optical dispersion sensing pixel for generating optical dispersion biometric data comprising subdermal structure data based upon dispersed light from the user'"'"'s finger;
said processor further comprising a matcher for determining a match between the subdermal structure data of the user'"'"'s finger and stored subdermal structure data for an enrolled user.

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.
