Multispectral Biometric Sensors
First Claim
1. A portable electronic device comprising:
- a body;
a platen adapted for placement of a purported skin site by an individual and integrated within the body;
an illumination source;
an imaging system; and
a controller interfaced with the illumination source and the imaging system, the controller including;
instructions to illuminate the purported skin site under a plurality of distinct optical conditions during a single illumination session;
instructions to derive a multispectral image of the purported skin site from light received by the imaging system after scattering from the purported skin site for each of multiple of the plurality of distinct optical conditions;
instructions to perform a nonbiometric function with the imaging system.

Abstract
A biometric measurement system has a platen, an illumination source, a light detector, and a controller. The controller is interfaced with the illumination source and the light detector. The controller has instructions to illuminate a purported skin site of an individual under distinct optical conditions during a single illumination session while the purported skin site is moved over the platen. The controller also has instructions to derive a multispectral image of the purported skin site from light received by the light detector after scattering from the purported skin site for multiple distinct optical conditions while the purported skin site is moved over the platen.

22. A method of performing a biometric measurement on an individual, the method comprising:
-
illuminating a purported skin site of the individual under a plurality of distinct optical conditions during a single illumination session while the purported skin site is moved over a platen; and
receiving light scattered from the purported skin site separately for each of multiple of the plurality of distinct optical conditions while the purported skin site is moved over the platen to derive a multispectral image of the purported skin site. - View Dependent Claims (23, 24, 25, 26, 27, 28)
