Abstract
Abstract A scanning arrangement in which the scanning speed at right angles to line direction is selected so that every line becomes scanned anew by the following element in picture direction. Reproduction is carried out by way of a series arrangement of luminous diodes. The light-emitting diodes (LEDs) are arranged geometrically corresponding to the detector array. For scanning the thermal picture, use is made of a polygon prism permeable for thermal radiation and beams; for reproduction use is made of 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 is achieved by turning both polygons and scanning in picture direction is achieved by tilting the pivot axis.
