摘要： In order to provide an imaging apparatus that uses an electron-bombarded multiplying tube with an internal solid imaging device with a long life, improved S/N ratio, high resolution, and moreover high sensitivity, an electron-bombarded multiplying tube with a photocathode 13 and a back-illuminated FT-CCD 11 sealed in a vacuum vessel is used as an imaging element. The vacuum vessel is made from a faceplate 12, a ceramic tube 16, and a ceramic stem 17. The photocathode 13 emits photo-electrons from a surface opposite from the incidence plane, in accordance with incident light. The FT-CCD 11 has an incidence plane disposed in the pathway of photo-electrons from the opposite surface. An imaging portion 11a of the FT-CCD 11 has pixels in the vertical direction in the same number as or in greater numbers than the number of output scan lines. A transfer electrode of the imaging portion 11a is constantly applied with a negative voltage during an image accumulation period. By this, dark current can be controlled, the S/N ratio can be improved, resolution can be maintained, and sensitivity can be improved.

摘要： The device comprises a grid of photodetectors which is coordinated with a grid of light-emitting picture elements. The light emitted by at least one of the picture elements is reflected to at least one of the photodetectors when an object approaches the device. The output signals produced by the photodetectors indicate which of the photodetectors have received reflected light.

摘要： An imaging apparatus comprising an electron-bombardment multiplier which is provided with a built-in charge-transfer solid-state imaging device having a high resolution, a high sensitivity, an improved S/N ratio, and a prolonged life time, wherein as an imaging element, an electron-bombardment multiplier is used which includes a vacuum enclosure made up of an input surface plate (12), a ceramic side tube (16), and a ceramic stem (17) and containing a photocathode (13) capable of emitting photoelectrons from the opposite surface to the incident surface in response to light incidence and a back-incidence FT-CCD (11) provided with an incidence surface in the traveling path of photoelectrons emitted. The number of pixels in the vertical direction of an imaging section (11a) of the FT-CCD (11) is equal to or more than the number of output scanning lines. A negative voltage is always applied to the transfer electrode of the imaging section (11a) during the image storage period. Consequently, the dark current is suppressed, the S/N ratio is improved, the resolution is maintained, and the sensitivity is also improved.

摘要： A method and system are provided for a photocathode-based display system in which light emitted from an electroluminescent (EL) material (35) is focused into parallel light rays and directed towards specific portions of phosphor (70) in the output display portion of the system. The light is focused and directed prior to striking photocathode material. In one embodiment, the light is focused using a micro lens array (100), comprising a plurality of micro lenses, each micro lens having a focal length. The micro lens array is placed approximately one focal length away from the EL material and before the photocathode material. Thus, dispersed or divergent light is focused and directed to desired portions of phosphor to produce a higher quality display.

摘要： A multi-function day/night observation, ranging, and sighting device (10) with active acquisition of optical targets includes a single objective lens (28) and a single eyepiece lens (30) and provides an image of a scene. The single objective lens leads to a visible-light first optical path that converges with an invisible-light second optical path at a reticule plane. The invisible-light second optical path includes an image intensifier tube (50) providing a visible image. Pulses of laser light (22) are projected into the scene via the single objective lens (28), and the image intensifier tube (50) is used as a detector.
