Sunnyvale, CA (PRWEB) February 28, 2017
Osram Opto Semiconductors is expanding its Oslux product family for biometric security solutions with a specially designed variant for facial recognition. This compact infrared LED (IRED) ensures uniform illumination of facial features for high image quality. Osram will be presenting the new SFH 4796S at the upcoming Mobile World Congress.
A facial recognition system scans the user’s face and detects typical features independent of facial expressions. Accurate and reliable identification of these features requires high-quality images and even, bright illumination of the face, without shadows. Generating additional infrared illumination allows the system to safeguard laptops and tablets effectively in a wide variety of lighting conditions.
Boosting system efficiency with Oslux
Osram Opto Semiconductors’ new SFH 4796S IRED, based on its proven Oslux family, features a unique, low-profile design that enables a narrow emission angle. This angle ensures the light generated hits exactly the point where illumination is required, so the overall system operates extremely efficiently. Oslux IREDs are based on an internal reflector and a specially adapted, integrated lens; the flat component surface offers a significant design advantage in facial recognition applications.
Outstanding facial illumination for reliable recognition
Osram’s SFH 4796S features an emission angle of ±40°, ideal for the field of view required by facial recognition systems. Thanks to specially adjusted internal reflectors and lenses, the IRED achieves extremely even illumination of the face. “We can build on our in-depth knowledge around the interplay between chip, package, reflector and optical elements,” explains Eric Kuerzel, Product Marketing Manager at Osram Opto Semiconductors. “Adding this new device to the family allows us to offer a broad portfolio specifically for the Oslux package, now also encompassing dedicated solutions for facial recognition.”
The SFH 4796S is based on a highly efficient chip featuring nanostack technology. At 1 amp current, the IRED generates optical power of 800 milliwatts (mW), ensuring ample illumination for its identification applications. It features a radiant intensity of 550 milliwatts per steradian (mW/sr). The component is just 1.4 millimeters high, with a footprint measuring (3.5 by 3.5) mm2. At a wavelength of 850 nanometers (nm), the light emitted by the SFH 4796S does not dazzle users and is simply perceived as a weak red glow, giving an indication that the facial recognition function is currently active. The sensitivity of camera sensors in this spectral range remains good.
