OSRAM’s New Infrared LED Enables 2D Facial Recognition on Mobile Devices
Synios P2720 uses longer infrared wavelengths with increased sensitivity to identify user’s face to unlock device
Sunnyvale, CA – OSRAM Opto Semiconductors, a leading lighting and technology company, today launched its Synios P2720 LED, which gives mobile devices like smartphones and tablets 2D facial recognition capability. When someone tries to access a device fitted with this technology, an infrared light illuminates the user’s face and an IR camera takes a photo to analyze his or her two-dimensional features. The system then compares the photo to previously stored images to determine whether or not it is the approved user. If various data points match, such as mouth width, length of the nasal ridge and distance between the eyes – the device unlocks. In addition to 2D facial recognition, mobile devices can be accessed in a variety of ways: by password, fingerprint scan and iris scan to ensure optimum device security.
Using a wavelength of 940 nm, Synios P2720 reduces the red glow that can occur with infrared light sources in the short-wave infrared range. Up to now, IR cameras were only suitable if the light source had a wavelength of 850 nm. The cameras have been further enhanced to give them greater sensitivity in longer wavelength ranges allowing 940 nm light sources to be used, which improves the overall performance of the system.
Bright and uniform illumination of the user’s face or eyes is particularly important for facial recognition and also for eye-tracking systems. Synios P2720 offers impressive performance with an output of 1,150 mW at 1 A. Thanks to this high overall output, it has a radiant intensity of 360 mW/sr.
The new Synios P2720 has the same footprint as the 850 nm version. Measuring only 2.0 mm x 2.75 mm x 0.6 mm, the IRED is ideal for space-critical applications. It has no optics, which keep its dimensions compact, and allows customers to install secondary optics in line with their requirements.
“Security is one of the most important issues today for mobile device users. That is why we are committed to providing components that push biometric identification to the next level,” explained Karl Leahy, Director of Infrared Products at OSRAM Opto Semiconductors. “Synios P2720 is ideal for 2D facial recognition because of its powerful and bright IRED that completely illuminates the facial characteristics of users, ensuring ultimate security when accessing the device.”
This IRED for 2D facial recognition is the latest addition to OSRAM Opto Semiconductors’ existing portfolio for biometrics. The new Synios P2720 is already available for initial customer projects.
The first infrared LED with 940 nm for 2D facial recognition provides the basis for high quality IR camera images and reduces red glow.
Synios P2720 from Osram provides bright and uniform illumination of the user’s face for 2D facial recognition.
