ABSTRACT:
A picture analyser tube with streak compensation constituted by a light intensifier tube structure comprising a photocathode (1) associated with an acceleration grid (2) and a microchannel plate (3) associated with an acceleration grid (4) coupled to an electron-sensitive (6) or photosensitive objects (7) CCD matrix. The wire compensation effect is obtained, for example, by deflecting the electron beam issued by the photocathode (1) by means of electromagnetic coils (5) traversed by currents the intensities of which are controlled in order that the deflection movement of the said beam is opposite to the movement of the picture during the duration of the passage of the object in the field of view of the device. The picture is thus immobilized in the plane of the CCD detector.
