| has gloss | eng: Chemical imaging is the analytical capability (as quantitative - mapping) to create a visual image from simultaneous measurement of spectra (as quantitative - chemical) and spatial, time informations. The technique is most often applied to either solid or gel samples, and has applications in chemistry, biology , medicine , pharmacy (see also for example: ), food science, biotechnology , agriculture and industry (see for example: and ). NIR, IR and Raman chemical imaging is also referred to as hyperspectral, spectroscopic, spectral or multispectral imaging (also see microspectroscopy). However, other ultra-sensitive and selective, chemical imaging techniques are also in use that involve either UV-visible or fluorescence microspectroscopy. Chemical imaging techniques can be used to analyze samples of all sizes, from the single molecule to the cellular level in biology and medicine , and to images of planetary systems in astronomy, but different instrumentation is employed for making observations on such widely different systems. |
