ABSTRACT:
An imaging system is provided which comprises an objective lens arrangement, a linear array of detector elements within a detector the array comprising a row of time delay an integrate (TDI) channels and a scanning optic arranged to scan an image over the array detector elements, the system further comprises means for rotating the scanning optic about an axis (N) normal to an optical surface of the scan optic when the scan optic is in the center of its field of view position, the scan optic being rotated about this axis (N) in dependence on the rate at which the imaging system is panned across a scene, such that a received image is vector scanned across the linear array of detector elements to compensate for loss in image resolution due to the panning action of the imaging system occurring during the period in which an image frame is detected.
