Abstract
A device for reading detector arrays with TDI effect comprises an assembly of lines of detectors each integrating its own contribution during an integration time, with each contribution corresponding to an image in one of an array of elementary circuits. A demultiplexer directs the contribution of each detector into a first elementary circuit determined by this detector and the number of the current image. A summing device, executes the sum of the contribution of the detectors consisting in choosing, for each detector, a second elementary circuit determined in function of the number of the current image and of the detector considered and in executing the sum of these elementary circuits so as to carry out the TDI effect on the detectors in such a manner as to obtain the contribution of the detector line.
