Abstract
An infrared thermographic optical scanner is comprised of a first optomechanical device fitted with an entrance objective, at least a raster scan element, and a plane of infrared detectors on which the infrared radiation is focused in the form of lines. Further, there is provided a second optomechanical device made up of an orientable tilted periscope-head mirror and a derotator. The derotator is maintained clamped with respect to the head mirror coupling means for operation in the panoramic mode in a predetermined first angular position such that all lines scanned are parallel to each other, the raster scanning movement being obtained by maintaining the position of the raster element fixed, and by simultaneously causing the rotation of the head mirror, and at half-speed, causing the rotation of the derotator.
