摘要： An image intensifier tube includes a photocathode (20) with an active layer (52) providing an electrical spectral response to photons of light. The photocathode (20) also includes integral spacer structure (42) which extends toward and physically touches a microchannel plate (22) of the image intensifier tube in order to establish and maintain a desirably precise and fine-dimension spacing distance nullGnull between the photocathode and the microchannel plate. A method of making the photocathode and a method of making the image intensifier tube are described also.

摘要： A camera includes a photocathode operable in a night mode wherein electrons are generated in response to incident light, an active pixel sensor including an array of pixels for sensing electrons in the night mode, a power supply for energizing the photocathode in the night mode in response to a control signal, and a power supply control circuit for providing the control signal to the power supply in response to a sensed incident light level. The control signal may be a gating signal having a duty cycle that increases as the sensed incident light level decreases. The camera may be operable in a day mode wherein a fraction of the incident light is transmitted through the photocathode and is sensed by the active pixel sensor. The camera may further include an electron shielded light detector. A light detector signal generated by the electron shielded light detector may be used to control switching between the day mode and the night mode.

摘要： A multi-function day/night observation, ranging, and sighting device with active acquisition of optical targets includes a single objective lens and a single eyepiece lens and provides an image of a scene. The single objective lens leads to a visible-light first optical path and to an invisible-light second optical path. The invisible-light second optical path includes an image intensifier tube providing a visible image. The first and second optical paths converge with visible images provided by each pathway being overlaid at a reticule plane. A single light path leads from the reticule plane to the eyepiece lens. A laser provides pulses of laser light projected into the scene via the single objective lens, and the image intensifier tube is used as a detector for a portion of the laser light pulses reflected from an object in the scene in order to provide both a laser range finding function and an active optical target acquisition mode. The device includes a light-emitting display visible through the eyepiece lens providing ranging information superimposed over the image of the scene as seen by a user of the device. Methods of the device's operation are also disclosed.

摘要： A feeble light measuring device comprising a photon counting tube, an image detector and a signal processor. The photon counting tube includes a photocathode for generating an electron upon an incidence of light to be measured, an MCP for multiplying the photoelectron from the photocathode and a phosphor screen for converting the photoelectrons multiplied by the MCP into a light image such as luminous spots. The MCP is not saturated by an incidence of single photoelectron. Thus the spread of the luminous spot corresponding to the single photoelectron is very small. The image detector converts the light image from the photon counting tube to electric outputs the signal processor removes noise components of the electric outputs from the image detector to extract signal components of the electric outputs.

摘要： Metal parts of an image intensifier tube which are exposed to a high voltage are coated with a layer of aluminum phosphate glass in order to preclude local discharge phenomena; the aluminum phosphate glass can be deposited in a thin, uniform layer already at a comparatively low flow temperature. Because the layer is thin, it is not necessary to take into account differences in coefficients of expansion, so that a high degree of freedom is achieved as regards the choice of materials for the metal parts.

摘要： The image intensifier (22) of night telescope (12) is protected by a deactivate circuit (FIG. 4) which is in series with an off-on switch (S) between a source of electrical energy (28) and the image intensifier (22). The light sensor (26) measures ambient light. If the light level is below a predetermined light level, at which it is safe to operate the image intensifier (22), the light sensor (26) does not conduct. This causes an amplifier circuit (A-1, A-2) to deliver a negative voltage to the base of a transistor (Q-1). This enables the transistor (Q-1) to transmit electrical current from the source (28) to the image intensifier (22). Whenever ambient light exceeds the predetermined light level, the photoconductive sensor (26) conducts. In response to this happening the amplifier circuit (A-1, A-2) delivers a positive voltage to the base of the transistor (Q-1). In response, the transistor (Q-1) becomes incapable of transmitting a current onto the image intensifier (22).
