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.
