ABSTRACT:
The invention relates to a shooting target.
The signal plate covering one of the faces of the actual target is subdivided into a plurality of electrically independent elementary signal plates in order to reduce the stray capacitance during the sampling of the signal on said plate. According to a preferred arrangement, these elementary plates are oriented in the same way as the scanning lines by the reading electron beam. This reading is performed either by a single beam or by a certain number of independent beams each covering a portion of the target.
The applications are the same as in the prior art and in particular to infrared photography.
