Spectral imaging

Spectral imaging is a branch of spectroscopy in which a complete spectrum or some spectral information (such as the Doppler shift or Zeeman splitting of a spectral line) is collected at every location in an image plane. Applications include astronomy, solar physics, analysis of plasmas in nuclear fusion experiments, planetology, and Earth remote sensing.

This is often referred to as hyperspectral imaging; see hyperspectral imaging for more information.
