Table 3-2 MSI Spectral Bands Characteristics and Specified Performance
3.5.2.2 Measurement Geometry
The MSI instrument design has been driven by the large swath requirements together with
the high geometrical and spectral performance of the measurements.
It is based on a push-broom concept, featuring a Tree-Mirror-Anastigmat (TMA) telescope
feeding two focal planes spectrally separated by a dichroic filter.
Figure 3-4 depicts the internal configuration of the MSI showing the TMA telescope
configuration and its optical path construction to the SWIR/VNIR splitter and focal planes.
Two distinct arrays of 12 optical detectors mounted on each focal plane cover respectively the
Visible and Near Infra Red (VNIR) and Short Wavelength Infra Red (SWIR) channels.
The 12 detectors on each focal plane are staggered-mounted to cover altogether the 20.6º
instrument field of view resulting in a compound swath width of 290km on the ground-track.
