Iris Capturing Under Bright Sunlight Conditions

Left and right images are taken under identical environments of more thanover 100,000 lux. The left iris image was captured with a conventional iris camera, whereas the right image was with IriTech's outdoor capturing technology integrated camera. The left iris image shows reflections that will likely degrade the matching accuracy, whereas the right image does not have any reflections.

Osram New IR LED Boosts Electro-Optical Efficiency by 48%

The new Oslon Black SFH 4715A boasts a typical electro-optical efficiency of 48 percent – a figure never before achieved with opto-electronic elements – and thanks to the associated huge reduction in cooling requirements, it has a much longer service life, too. In other words, this latest member of the infrared LED (IRED) family is reaching previously unattainable figures. But this is not the only new product in the Oslon Black family from Osram Opto Semiconductors: The SFH 4716A has a beam angle of 150° permitting particularly narrow-angled imaging for camera-based lighting applications by using reflector optics.

LED Pioneer Jerry Woodall Turns to Clean Energy

You might not know what "lattice-matched heterojunctions" are, but if you stopped at a new stoplight, played a DVD or used a laser pointer, you've made use of technology pioneered by Jerry Woodall, distinguished professor of electrical and computer engineering at the University of California, Davis. Woodall's work, begun in the 1960s at IBM Research, is the basis for cheap, energy-efficient light-emitting diodes, or LEDs, and lasers.

Everlight Receives Considerable Orders for IR LEDs from Mainland Chinese Suppliers

Recently, Everlight has enjoyed considerable business for its infrared (IR) LEDs from many mainland Chinese suppliers of touch-screen modules for Win 8 PCs. Based on these orders, industry executives estimated IR LEDs as a percentage of Everlight’s revenue to further increase next year from current 25%. according to Everlight’s spokesman, B.Y. Liu, the company has so far this quarter landed considerable orders from touch-screen module suppliers that will likely shore up the company’s revenue for Q4 to Q3. Usually, the fourth quarter is a low s...
