    • A device for photogrammetric evaluation of stereo-couples of photographs which are scanned light electrically and, in order to obtain height coordinate values, are evaluated by correlation.The device is particularly useful in the evaluation of aerial photographs. To reduce correlation errors due to interfering signals obtained from different correlator signal channels and, hence, to increase the precision of a correlation operation, at one time only the informations from one correlator signal channel in each of the two scanning channels are exploited to obtain the informations from the scanned stereo-pair of photographs.Therefore, it is desireable that, in the course of the correlation operation, the highly resolving correlator signal channels are predominantly and for a considerable long time employed to correlate the informations. According to the invention gate circuits are inserted between the correlator signal channels and the discriminator.The signal channels are successively triggered via the gates by operation of a pulse distributer connected to a clock pulse generator in a sequence of the rising resolution of said channels.
