Scanning speed at right angles to scanning line direction becomes so selected that every line becomes scanned anew by way of the following element in picture direction. Reproduction is carried out by way of a series arrangement of luminous diodes. The luminous diodes are arranged geometrically as to the detector arrangement. For scanning the thermal picture, there becomes used a polygon prism permeable for thermal radiation and beams and for reproduction there becomes used a polygon prism permeable for visible radiation or beams. Both prisms are located on the same pivot axis and the scanning of the thermal picture, as well as the reproduction of the visible picture in line direction occurs by way of turning both polygons and scanning in picture direction occurs by tilting of the pivot axis. |
