Variability must be avoided for OEM instrument developers who must guarantee an answer based on the quality of a Raman spectrum. These answers are important to their customers and those influenced by ...

Raman spectroscopy, compatible with molecular and material samples, is one of the most popular quantitative and qualitative spectroscopic techniques. A sample has a distinct Raman “fingerprint” that ...

Astronomical measurements of motion frequently utilize the Doppler effect, observing shifts in wavelength (or frequency) of emitted waves from moving sources, analogous to a changing siren pitch.

Non-line-of-sight imaging can detect objects even if they are behind a wall. Researchers have now extended this method from visible wavelengths into the near and mid-infrared region. WASHINGTON — ...
