Photoacoustic tomography of fingerprint and underlying vasculature for improved biometric identification
Abstract Capitalizing on the photoacoustic effect, we developed a new fingerprint sensing system that can reveal both fingerprints and underlying vascular structures at a high spatial resolution. Our system is built on a 15 MHz linear transducer array, a research ultrasound system, and a 532-nm puls...
