The bundle is then reshaped; the individual fibers are aligned at the entrance slit of a spectrometer, dispersing the light on a detector.

[1] This technique is closely related to integral field spectrography (IFS), more specifically to fiber-IFS.

The LAMOST moves its 4000 fibers separately within designated areas for the requirements of a measurement, and can correct positioning errors in real time.

The Hubble Space Telescope has been operating the NICMOS (Near Infrared Camera and Multi-Object Spectrometer)[20] from 1997 to 1999 and from 2002 to 2008.

The James Webb Space Telescope's NIRSpec (Near-Infrared Spectrograph) instrument is a multi-object spectrometer.
