Biometrics Fingerprint Scanner

- Ultrasound Image Processing
- FPGA Tone Burst Control
- Low-Noise Analog Interface
- Custom Multi-Board System
Overview
A client chose Nuvation to create an ultrasound fingerprint scanner. Nuvation designed three custom boards, implemented a tone-burst generator in an FPGA, and developed a suite of embedded software for board support and system integration.
