Abstract

An optical system for motion compensation of line scanners to improve the resolution in one or more spectral channels, the system having a motion of its own or being arranged on a moving observation platform. A multi-faced prism is provided which is associated with the optical system and rotates about its central axis at a settable rotational speed. The integration time for imaging a radiation source is increased due to the rotation of the prism in a direction opposite the track or flight direction.
