  • Low light level, high resolution imager using phosphor screen provided with a metal layer for controlling integration cycle of photosensitive matrix array
    Patent number: 5294788
    Abstract: The present invention relates to a low level, high resolution imager of the type comprising a light-amplifier tube (300) including a photocathode (310), at least one microchannel slab (330) serving as an electron amplifier, and a light-emitting phosphor screen (340) provided with a metal layer (342), an electron camera (400) comprising a photosensitive matrix array (410) suitable for transforming a received photon into an electron, and control means (700) for the electron camera, characterized by the fact that the control means (700) comprise an amplifier (710) responsive to the electrons collected on the metal layer (342) of the light-emitting phosphor screen (340) to control integration cycles of the photosensitive matrix array (410) in repetitive one-shot mode synchronized on the appearance of photons at the input of the light-amplifying tube (300).
