Abstract

We have acquired 3-D biometric images using digital holography. This was accomplished using eyesafe (~1550 nm) telecom fiber lasers at two wavelengths. The two images were aligned, with respect to phase, and then subtracted to obtain a wrapped image. The wrapped image is then further processed to reduce noise that interferes with the unwrapping process. Some example biometric images are presented.
