Abstract
Systems and methods are disclosed for obtaining at least a pair of biometric traits of a person and without contact with the person. In one embodiment a system is disclosed which makes use of a plurality of illumination modules and an imaging module, where a single image is acquired with a color encoded imaging sensor. Parallel and orthogonally polarized images are obtained by at least one sensor of the imaging module from illuminations produced by the illumination modules. A processing subsystem uses mathematical applied operations between the acquired images to selectively produce at least one image of at least one specific biometric trait, such as a finger print, a palm print, a finger-vein, a palm vein, or hand geometry. The biometric trait can be subsequently used for biometric verification and identification.
