Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...
Researchers have developed a fast and accurate flexible tactile optical sensor capable of reading Braille. The technology could enable smart readers that convert Braille to speech or text, helping to ...
Avago Technologies has announced a series of small form factor (SFF) optical mouse sensors with an integrated chip-on-board (COB) LED illuminated optical navigation system that is the thinnest in the ...
There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...
Aging degradation and seismic damage of civil infrastructure pose a serious problem for society. One promising technology for monitoring the condition of structures is optical fiber sensing. By ...
Carbon nanotube: these structures have been used to create a new and flexible light sensor. (Courtesy: iStock/theasis) A flexible, ultrathin optical sensor that uses carbon nanotubes to convert light ...
