Blinking replaces the double-click The SFH 4770S from Osram Opto Semiconductors is currently the most compact infrared LED (IRED) in the high-power class. Its low height is of particular benefit in smartphones and tablets. The high optical output of typically 1200 milliwatts (mW) and broad emission characteristics make this IRED ideal for facial recognition and eye-tracking systems which can activate applications in response to blinking instead of the usual double-click. The basis for the new record emitter is the Synios package which Osram introduced some time ...
