Abstract:
1. A system for capturing light from a holographic platen, the holographic platen being formed from a holographic element, onto an image sensor in order to generate a print image of a biometric object, comprising: a flatbed scanner including a scanning surface that supports the holographic platen and an image sensor; and a reference beam source that provides a reference beam to the holographic platen, wherein the holographic platen receives the biometric object on a top surface thereof, and wherein the reference beam interacts with the biometric object through reflection from the top surface of the holographic platen, such that, when the biometric object is present on the holographic platen, biometric information correlating to the biometric object is formed through frustrated total internal reflection and the holographic platen directs the biometric information onto the image sensor.
