3D Biometrics System

The 3D biometrics system was identified as a technology transition product, 4D then worked with the Army Research Laboratory (ARL) to develop and package a 3D fingerprint collection capability based on two-wavelength digital holography. 4D developed the system from a benchtop set-up to a transportable ready to use package. 4D rapid prototyped a hand-held imaging device that transmits short wave infrared (SWIR) laser light to illuminate the finger. The imaging device incorporates an LCD screen for aiming the illuminator and a SWIR detector to capture the raw data used to generate a holographic image. 4D packaged the processing computer, electronics, and power supplies in a ruggedized, waterproof container. The system demonstrated the ability to effectively collect 3D fingerprint images at a range of 18 inches.
