3D Sensing in Biometrics
Biometric authentication through facial recognition allows secure access to data on personal electronic devices. It also allows secure entry into private spaces such as in cars, homes or offices or into administrative areas restricted to public access such as in airports, stadiums or entertainment venues.
II-VI VCSEL arrays provide infrared illumination and structured light projection to enable biometric scans. Our optical filters isolate the returning VCSEL signal over a wide field of view to improve the sensors’ accuracy and sensitivity, whether in intense sunlight or at night time. Active coatings such as indium tin oxide (ITO) can also be deposited on our micro-optics in complex patterns and used to monitor light leakage from a physically damaged sensor.
