Biometrics comprises methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits. We would like like to hear from companies on the cutting edge of Biometrics using ultrasonic techniques
Example - Ultrasonic Finger Recognition
Optel: We design and manufacture elctronics for ultrasonic technology (PC-cards, pulser&receiver, amplifier), transducers, electronics for power ultrasound, scanning devices. We have large experience with ultrasonic holography (especially for fingerprint recognition). We uderstand us as an R&D oriented company, interested in developing new products. We have made many projects for different companies in the whole world.
We also manufacture ultrasonic sensors and transducers, ultrasonic testing, ultrasonic welder, ultrasonic inspection, ultrasonic measurement, ultrasonic circuit, ultrasonic probe, ultrasonic instrument, ultrasonic level sensor, fingerprint recognition with ultrasound
