integral field spectroscopy
binâbnemâyi-ye dorost-e meydân
Fr.: spectroscopie intégrale de champ
A technique in spectroscopy for recording a spectrum from each point of an extended object. The field of view image is divided into a multitude of small components using different methods, e.g. lenslet arrays, fiber bundles, or image slicers. From each component a spectrum is extracted or an image is reconstructed at a particular wavelength.
Fr.: spectroscopie multi-objets
A technique of spectroscopy using fiber optics whereby several objects distributed over the field of view can be observed simultaneously.
The study of spectral lines from different atoms and molecules. Spectroscopy is an important part of studying the physical and chemical properties of astronomical objects.
