Abstract
The camera system consists of a folded optical system that focuses object in the visible waveband on a plurality of CCD detector arrays (6). The camera system is a push-broom imager with a plurality of long, substantially linear CCD arrays (6) arranged orthogonal to the scan direction S. The camera system is capable of image resolutions down to 1 m from a space orbit.
Claims14
A camera system for scanning a remote object from space, comprising:
- a plurality of object detectors each comprising a pixellated array of charge coupled devices (CCDs) acting as a single detector channel;
- and
- a telescope arrangement of mirrors defining a folded optical path for focusing an object on the plurality of object detectors;
- wherein the number of CCD pixels of each object detector in a direction orthogonal to a scan direction of the camera system is greater than the number of CCD pixels in the scan direction;
- and
- wherein the plurality of object detectors are substantially in a line orthogonal to the scan direction.
