tof3D Sensing: Behind OLED 3D Imaging By trinamiX
trinamiX captures not only a 2D picture and a 3D depth map of the face, but also checks for “live skin” to recognize liveness in real-time. Spoofing the unlock system of a smartphone with a realistic full-face mask, 3D sculpture or even a detailed 2D printout becomes virtually impossible.
The hardware consists of just a standard CMOS sensor and a NIR light projector. The complete system can be mounted behind the smartphone display. The previously required smartphone notch is made obsolete.
“ We are very pleased to usher in this new era together with the smartphone OEMs,” says Stefan Metz, Director 3D Imaging at trinamiX. “ With our technology, users will no longer have to compromise as they benefit from the most secure privacy protection without sacrificing a user-friendly all-screen display. “
Trinamix currently has 150 employees.
“ We focus on material classification for smartphones,” Metz said. “ That means we can tell if it is human skin or something else, like plastic. “
