    Abstract: An apparatus, and a process, for reading a target of a camera tube. The apparatus includes circuits for scanning the inner surface of the target along a plurality of parallel lines. The scanning being done by an electron beam. Means for stabilizing each line of order n by a stabilizing scan of the electron beam to a value Vo. And means for reading the line of order n by a reading scan of an electron beam to a value V'o, after an integration time ti that is adjustable; and V'o being lower than Vo is absolute value.

    Abstract: Device for reading a picture pickup target and assembly constituted by the target and such a reading device. The target I takes the form of a matrix of detectors placed at the points of intersection of lines and rectangular columns. The reading device II comprises one input per line and for each line: (1) a channel A connected to said input wherein the signals of the points of the line are transferred in series and at the same time for all the columns in the line reading time t1; (2) a storage channel B into which the signals of channel A are transferred in parallel and stored; (3) an evacuation channel C into which the signals from channel B are transferred in parallel and from which they are transferred to a reading register with a single input, to an amplifier therefrom and to the reading apparatus. Storage in B enables the signals to be processed, in particular integrated throughout the time comprised between t1 and the register evacuation time.

    Abstract: A potential compensating device for resistive sensors of pyroelectric tubes uses an ionic effect. The sensors are swept by a beam of electrons emitted by the cathode of the tube. The sensor then has a front face at an electric potential different from the potential of its back face. The back face potential varies according to the intensity of thermal rays received. The front face of the sensor is bombarded by ions which result from collisions between gas molecules and beam electrons. The ions then raise the potential of points of the front face of the sensor. The compensating bombardment is carried out during a phase different from the measuring phase. The measuring phases and the compensating phases alternate during operation of the tube. The device enables the back face of the sensor to be at a higher potential than the one obtained without its use.

    Abstract: Electrical signals delivered by detectors at the surface of a first high-capacitance insulating layer which provides a separation between a first array of metallic electrodes and the detectors are collected by the electrodes by capacitive coupling. The first array of electrodes is electrically connected to a second array of electrodes having smaller dimensions. The two arrays are separated by a second insulating layer and the second array is located at the interface between the second insulating layer and the oxide layer which covers the semiconductor readout substrate.

    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.
