'''Spectrometry''' covers a wide range of measurement techniques, the core concept of which being that they determine the [[amplitude]] of individual [[frequency|frequencies]] of interest in the spectrum of a complex signal. That signal is most often in the [[electromagnetic spectrum]], but can also be acoustic. The term is sometimes used as a synonym for '''spectroscopy''', but spectrometry always is quantitative while spectroscopy may only look for the existence of spectral components.
'''Spectrometry''' describes quantitative spectroscopy — the analysis of absolute and/or relative contributions of frequency components to the spectrum of a given sample or object.
 
The signal of interest may be emitted by the subject, reflected by it, or selectively absorbed by it. Spectrometric information from multiple views of a subject may be used to construct images.
