integral field spectroscopy
  بیناب‌نمایی ِ درست ِ میدان   
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.

integral; → field; → spectroscopy.

multi-object spectroscopy
  بیناب‌نمایی ِ بس‌-بر‌آختی   
binâbnamâyi-ye bas-barxâti

Fr.: spectroscopie multi-objets   

A technique of spectroscopy using fiber optics whereby several objects distributed over the field of view can be observed simultaneously.

multi-; → object; → spectroscopy.

spectroscopy
  بیناب‌نمایی   
binânnemâyi

Fr.: spectroscopie   

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.

Spectro- combining form of → spectrum + → -scopy.
