Description
[Text Source: CNES, http://spot4.cnes.fr/spot4_gb/hrvir.htm ]

The HRVIR imaging instrument is designed to acquire, instantaneously, one complete line of pixels at a time covering the entire field of view. This is achieved using charged-couple device (CCD) linear array.

Special optical devices forming a so-called "spectral separator" separate the in-coming light (from target area on the ground) into four spectral channels.

The CCD linear arrays operate in the so-called "push-broom" mode. A wide-angle telescope forms an instantaneous image of adjacent "ground patch areas" on a row of detectors in the instrument's focal plane.
