Data acquisition device for optical detection and storage of visually marked and projected alphanumerical characters, graphics and photographic picture and/or three dimensional topographies

The data acquisition device for optically acquiring and storing alphanumerical characters, graphics and photographic pictures and/or three-dimensional topographies arranged in the plane of a picture in which

• a projecting device (15, 115) provided with a radiation source (17, 117, 228) for selecting a freely selectable section (19) of the image plane or topography within a preset maximum section, projects light onto said section (19);
• an optical unit (4, 104, 204, 307) captures the light reflected by said section (19) and reproduces it on a screen detector (14, 114, 208, 308) converting the light into a sequence of electronic signals;
• a motion detector (2, 202) for recording the given position of the data acquisition device is provided with detecting means (229, 229′, 229″, 229′″) for contactless detection of the movements of the data acquisition device (1, 200) in any desired direction, said direction being variable during acquisition, and converts the given movement of the data acquisition device (1, 200) into synchronizing signals;
• a signal processing unit (7, 207, 318) converts the signals of the screen sensor (14, 114, 208, 308) with the help of the synchronizing signals into character code-independent information packets with retention of the entire original information of the section (19) and recallably files said information packets in a memory unit for occasional further electronic processing.
