SUNNYVALE, CA — Oct. 4, 2012: The foundation technology developed at SBG Labs has not only enabled the development of waveguide-based display applications, but the architecture can also be used to enable a range of biometric applications such as fingerprint scanners used by Department of Homeland Security. The National Institute of Standards and Technology (NIST) agrees and awarded SBG Labs a SBIR grant to pursue development.
Current fingerprint scanners use lasers, optics and rotating prisms to capture an image of the fingerprint, but such devices are unsuitable for portable scanning machines because of their bulk, power consumption and cost. SBG Labs has alternately developed a thin waveguide based solution that electronically scans infrared light over the surface, much like a typical color copier, but with no moving parts. This low power solution can connect to a laptop or tablet to enable collection and processing of fingerprints on a portable basis, making it fully compliant with FBI standard. The DigiLens® prototype scanner under development embeds a series of high resolution Switchable Bragg Gratings in the planar waveguide, where a sensor captures the reflected image of the fingerprint one line at a time to the FBI 500 line per inch standard.
The SBIR grant awarded by NIST funds further software development to ensure compliance to the new NIST standard covering 4G cellular networks linked to the FBI fingerprint reference database. SBG will be marketing its breakthrough scanner to leading security corporations and direct to governments worldwide.
