Abstract
The present system provides a thermal imaging device including a detector array responsive to thermal infrared radiation. The detector array has a linearly-arrayed plurality of spaced-apart detector elements defining cooperatively a length dimension for the detector array. Each of the plurality of detector elements provides a corresponding individual electrical signal indicative of the thermal infrared radiation incident thereon. The detector elements vary from one another in the plurality of detector elements, and the thermal imaging device responsively provides a visible-light image replicating a viewed scene. The thermal imaging device includes a scanning device scanning the viewed scene across the plurality of detector elements in a direction generally perpendicular to the length dimension. The scanning device includes a first portion scanning the viewed scene across the entire plurality of the plurality of detector elements, and a second portion scanning the viewed scene across the plurality of detector elements with transposition of the viewed scene such that a portion of the viewed scene scanned by the first portion across a certain detector element is scanned across a detec…
