    Abstract: A light and charged particle image intensifier (10) receives incident image conveying light or charged particles {«incident beam») (12) and provides to data processing and video equipment signals from which the image conveyed by the incident beam (12) can be constructed and displayed. The beam (12) that is being processed includes visible light reflected from objects and X-ray radiation that has been passed through an object such as a human body. The image intensifier includes a scintillator (14) and photocathode unit (16) for converting the incident beam (12) to photoelectrons (18) and a charge-coupled device («CCD») (52) for detecting the photoelectrons (18) and transmitting to the data processing and video equipment information relating to the quantity or energy level as well as the location of the electrons (18) impinging on the sensing areas (54 or Sl to SN) of the CCD (52). From this information, the data processing and video equipment can reconstruct the image conveyed by the incident beam (12). The sensitivity of the device is increased either by imposing an electric field across the photocathode (16) and the CCD (52) to accelerate the photoelectrons or by placing a micro channel processor («MCP») (20) between the photocathode (16) and the CCD (52) to increase the number of electrons that impinge on the CCD (52). Alternately, a silicon diode target (42) can be used instead of a CCD (52) to intercept the electrons and an electron beam gun (44) can be used to detect the location and intensity of the charges created on the target (42) by the impinging electrons. Finally, a grid (24) having a number of windows can be used instead of a CCD (52) or a silicon target (42) to detect the location of the electron streams and a photoanode (25) can detect their intensity.

    Abstract: An electron beam head for reproducing magnetically recorded video signals wherein magnetic fields from the record medium are channeled to the interior of the envelope to deflect the primary electrons transversely to the scanning direction of the beam. In one embodiment, the sensing electrodes are at opposite sides of the magnetic field region at an end wall of the envelope, while in another embodiment the primary electron beam passes through the openings in a grid of magnetic wires so as to interact with the magnetic fields therebetween, electrostatic deflecting means serving to deflect the electron beam through a substantial angle as it leaves the grid so as to impinge on sensing electrodes remote from the grid. In a third embodiment, secondary electrons are conducted into a branch tube extending from the main envelope and a single electrode senses the degree of deflection of the secondary electrons by the magnetic fields permeating the secondary emission region.
