Abstract
Thermal imaging apparatus particularly but not exclusively for use on an aircraft with a head-up display is provided with signal processing means which progressively expands or compresses the image in the vertical and/or horizontal direction to compensate for parallax arising from the difference in the positions of the observer and the scanner. The adjustment is performed, in the preferred embodiment, as a function of height of the aircraft.
