Researchers at the US National Institute of Standards & Technology, NIST have developed a compact, high-accuracy, point-of-use high-power laser power meter in the form of a folding mirror. Called ...

To effectively control increasing number and diversity of industrial tasks now performed by lasers, manufacturers must ensure that their lasers fire at the correct power. But to date, there has been ...

NIST researchers have developed a compact, high-accuracy, point-of-use high-power laser power meter in the form of a folding mirror called “Smart Mirror,” making in-situ, real-time measurement of ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

Fig 1. The MEMS pressure sensor detects the tensile stress on a thin silicon membrane that changes the piezo-resistance of elements on the membrane’s surface. Fig 2. The MEMS sensor’s piezo-resistive ...

Military researchers are now proving that drones do not always need to carry their own fuel or batteries. In recent tests, ...

In the most recent tests, the system successfully transmitted lasers to aircraft flying up to 5,000 feet (1,524 meters), the ...

Researchers describe a new wireless laser charging system that overcomes some of the challenges that have hindered previous attempts to develop safe and convenient on-the-go charging systems. With ...

Researchers have developed a smaller, faster and more sensitive laser power meter in the form of a folding mirror they call a 'smart mirror.' High-power lasers are now widely used in additive ...
