UTA develops light-intensity-independent position sensor

17 Jun 2002

Mechanical engineering researchers at the University of Texas (Austin, TX) and Gillette (Boston, MA) have developed a silicon-diode sensor to measure six-degree-of-freedom position-independent light levels. Sensing is based on reflectance of light from the desired object and requires simple optics. As long as the signal is above the noise floor, the sensor can operate by detecting the difference in signal intensities. Applications include robotics, machining, and assembly.
