Measurements of the intensity of light at different wavelengths can be made more accurately now, thanks to a new, simple method for correcting common instrument errors. The new method, developed by ...

Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical “hotspot” of a ...

A new method enables calibrating entire waveforms -- graphical shapes showing how electrical signals vary over time -- rather than just parts of waveforms as is current practice. The new method ...

National Institute of Standards and Technology (NIST) researchers have developed a method for assessing and selecting optimal antenna design for future fifth-generation (5G) cellphones and other ...

Microphone calibration is an important issue for noise monitoring stations, sound power measurement systems and audiometric equipment, among other applications. Traditional calibration methods can ...
