Reproducing picture on photosensitive material - representing image on CRT screen for settable time and forming sharp image on material by focussing lens

Following elapse of the first partial period of illumination, the image (picture) copy is portrayed again on the crt screen, but shifted slightly in the direction of movement of the photo-sensitive strip of material, and the displaced image (picture) copy is then reproduced again on the photosensiti...

Beschreibung
Zusammenfassung:	Following elapse of the first partial period of illumination, the image (picture) copy is portrayed again on the crt screen, but shifted slightly in the direction of movement of the photo-sensitive strip of material, and the displaced image (picture) copy is then reproduced again on the photosensitive material (3). The latter is then moved to keep the reference cross (3b) in the same position for both partial illumination periods. Instead of the material being moved, the lens can be re-positioned, eg by a lifting magnet (4). ADVANTAGE - Eliminates interference spots on the photosensitive material during reproduction process caused by faulty phosphor points on crt screen.
