A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next ...

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 ...

I am always on the lookout for ideas for simple test and measurement instruments that can be used on my workbench. Over the years, I have built dozens of little test instruments and home lab ...

Folium Sensing transforms optical fibre cables into real-time distributed sensors for monitoring various critical ...

Mouser Electronics, Inc., is now supplying the new RPR-0730 photo reflector from ROHM Semiconductor. The RPR-0730 is an ...

In 1978, Dr Kenneth Hill, a Canadian physicist, first demonstrated the Fiber Bragg grating (FBG), an optical sensor able to reflect narrow wavelengths of light. During the 1980s, the technology was ...
