1. A system for obtaining images associated with at least a pair of biometric traits associated with a body part of a person, without contact with the body part of the person, the system comprising: a first illumination source configured to provide a first illumination at a first wavelength, and having a first polarization; a second illumination source to provide a second illumination at a second wavelength, and having a second polarization; a third illumination source configured to provide a near infrared (NIR) illumination, and having the second polarization; an imaging subsystem including a polarizer having the first polarization and a sensor system for capturing a plurality of acquired images, each one of said plurality of acquired images being specific to one of said illumination sources, as the illumination sources illuminate the body part; a processing subsystem configured to mathematically use at least two different ones of said plurality of acquired images associated with at least two of the illumination sources to generate at least one new image providing enhanced contrast of features associated with at least one of a surface biometric trait of the body part and a subsurface biometric trait of the body part; and wherein the processing subsystem is configured to at least one of mathematically subtract or divide, after normalization, one of the images from the plurality of acquired images, from a different one of the acquired images, to selectively obtain at least one of the surface biometric trait and the subsurface biometric trait.
