Title:
BIOMETRIC IMAGING DEVICES AND ASSOCIATED METHODS
Document Type and Number:
WIPO Patent Application WO/2013/010127
Kind Code:
A3
Abstract:
Systems, devices, and methods for identifying an individual are provided. In one aspect, a system for identifying an individual can include an active light source capable of emitting electromagnetic radiation having at least one wavelength of from 700 nm to 1200 nm, and an imager device positioned to receive the electromagnetic radiation upon reflection from an individual to generate an electronic representation of the individual. The system can include an image processing module functionally coupled to the imager device to processes the electronic representation into an individual representation having at least one substantially unique identification trait. The imager device can include a device layer having a thickness of less than about 10 microns, two doped regions forming a junction, and a textured region positioned to interact with the electromagnetic radiation, and can have an EQE of at least 33% for at least one wavelength of greater than 800 nm.
