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 ...

The National Institute of Standards and Technology (NIST) has unveiled a method for calibrating entire waveforms—graphical shapes showing how electrical signals vary over time—rather than just parts ...

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 ...

Laser measurement can calibrate a precision microphone as well as traditional techniques, according to the US National Institute of Standards and Technology (NIST). Such calibration is required in ...
