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 ...

A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

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 ...

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 ...

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 ...
