Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

Scientists have developed a real-time fiber-optic distributed sensing system for strain and temperature. The system requires light injection from only one end of the fiber and can achieve a sampling ...

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 ...

The Optipact motion sensors determine rotational or translational velocities of machinery or products in a wide variety of applications. The sensors are built around an optical system: The velocity of ...

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 ...

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 ...

Japanese researchers have devised a non-contact system for monitoring the vibrations of industrial robots as they operate, ...

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 ...
