Abstract
An image intensifier tube and a solid-state image pickup device are combined to form a unified image pickup device. A thin fiber plate with thickness of 0.5-1.5 mm is interposed between a phosphor layer of the image intensifier tube and a photosensitive layer of the solid-state image pickup device. A microchannel plate may be incorporated to multiply photoelectrons emitted from a photocathode.
Claims10
An image pickup device incorporated with an image intensifier tube, comprising:
- a photocathode section comprising a photocathode for emitting photoelectrons in response to an input optical image of an object;
- a fluorescent screen section comprising a phosphor layer for converting an electron image into an intensified optical image;
- a thin fiber plate for transmitting said intensified optical image;
- and
- a solid-state image pickup device for producing a video output signal in response to the intensified optical image transmitted from said thin fiber plate.
