Abstract
An image plane scanner concept has been evaluated for application to a medium resolution visible and infrared multispectral imaging instrument (MRVIR) that was originally planned to be flown on the french Earth Observation satellite SPOT-1. The instrument design in-cludes several distinctive features, in particular (1) an all-reflective Schmidt Telescope having 17° fov, (2) a 18 - objectives scan wheel supported on a magnetic bearing, (3) dichroic beam splitters, (4) cooled focal plane array for IR detectors, (5) CFRP structure , (6) semi-active thermal control. MRVIR is designed to provide 70 m ground resolution in bands 1-6 and 140 m in band 7 (thermal infrared). A relatively large swath width of 240 kms improves the repetition rate of the ground coverage.
