Abstract
The present invention is directed to a system and method for taking up an object space using a laser range finder and a scanning device for scanning the object space. Furthermore, there is a passive opto-electronic receiver having an associated scanning device. The scanning device(s) scans the object space for the range finder and the passive receiver synchronously and in phase. To each image element, a spatial angle is assigned for identification. The passive receiver, comprises an array of transducer, elements where the image angle of an individual element of the array corresponds preferably to the beam angle of the laser beam. A memory includes one cell per image element so that with each distance measurement the individual elements of the array can be read and their signals stored in the cells of the memory. With each distance measurement the assignment of the elements of the array to the cells of the memory is shifted by one so that the cell which had received the signals of a certain image element receives them anew and the signals received from different spatial angles add up in the cells during subsequent measurements.
