What is spectral measurement

Spectroscopy is a method of identifying substances and determining their chemical composition and relative content based on their spectra. It is an analytical method established on the basis of molecular and atomic spectroscopy which called spectroradiometer. Contains three main processes: ?energy provides energy; ?energy interacts with the measured substance; ?produces the detected signal. There are many classifications of spectroscopy.
