Laser-based optical sensors for mouse manufacturers
( 01 Sep 2005 )
Agilent Technologies’ laser navigation sensor technology is now available to mouse manufacturers worldwide. Three versions of the laserbased optical mouse sensors are being offered: one for highend cordless mice, one for high-end corded mice, and a version optimized specifically for the high-performance gaming environment. Laser illumination is superior to LEDbased illumination in that it reveals trackable surface structures the LED light source cannot uncover. Laser mice using this technology can easily track on painted metal, polished wood-grain surfaces, glossy photo paper, translucent plastic, frosted glass and many other previously difficult surfaces. A key component of the Agilent LaserStream technology is the company’s ADNV-6330 842nm wavelength VCSEL, engineered to provide a laser diode with a single longitudinal and a single transverse mode, which, in contrast to most oxide-based single-mode VCSELs, remains in singlemode operation over a wide range of output power. The low operating current of the ADNV-6330 allows lower power consumption in optical mice.
