摘要
The receiving optics consist of an astronomic (Kepler) telescope (10) with an objective (10a) with long focal length and an ocular (10b) with short focal length. This telescope system reduces the beam cross section in accordance with the magnification factor. As a result, a relatively small scanning element (rotating metal-coated prism 14) arranged in the parallel beam path of the ocular (10b) is obtained. In the common focal plane of objective and ocular at the location (Z) of the intermediate image, a field diaphragm (22) is arranged which masks out interfering radiation. This results in a high scanning efficiency. The invention is suitable for thermal imaging devices. IMAGE
