摘要:
An InGaAs Image Intensifier (“I2”) Camera (C) detects and forms an image (310) to be viewed. An InGaAs photocathode Image Intensifier (312) is used to pass an amplified signal (316) from a screen (320). The InGaAs image intensification tube (312) is optically coupled (328) to an imaging device (322) for passing output light. The output light (316) from the InGaAs tube (312) is transformed by an electronic circuit (322) producing a desired signal output (324). The signal output (324) from the electronic circuit (322) may be further enhanced into an enhanced signal output (310). The enhanced signal output may be formatted into a form for viewing or may be saved.

A method for detecting radiation is disclosed that includes forming a detector having a photocathode (22) with a protective layer (22c) of cesium, oxygen and fluorine; a microchannel plate (MCP) (24); and an electron receiver (26). Radiation is received at the photocathode (22). The photocathode (22) discharges electrons (34) in response to the received photons. Discharged electrons (34) are accelerated from the photocathode (22) to the input face (24a) of the microchannel plate (24). The electrons (34) are received at the input face (24a) of the microchannel plate (24). A cascade of secondary emission electrons (36) is generated in the microchannel plate (24) in response to the received electrons (34). The secondary emission electrons (36) are emitted from the output face (24b) of the microchannel plate (24). Secondary emission electrons (36) are received at the electron receiver (26). An output characteristic of the secondary emission electrons (36) is produced.

The present invention comprises a photon detector and image generator, which includes a photocathode that receives photons from an image. The photocathode discharges electrons in response to the received photons. A microchannel plate with an unfilmed input face and an output face receives the electrons from the photocathode and produces secondary emission electrons which are emitted from the output face. A display receives the secondary electrons and displays a representation of the image. The photon detector and image generator has a lifetime of more than 7,500 hours.

An improved microchannel plate (24) is disclosed. The microchannel plate has an input side (24a) and an output side (24b). A coating (32) is applied to the input side (24a) to increase secondary electron production and to prevent ions from leaving the microchannel plate (24) and damaging the photocathode (22).
摘要:
A sensor unit (F) has at least a first and second sensor (10, 12) arranged along a sensor axis (14). A head adapter (16) provides support to mount at least one selected device about a user's cranium (18). A securing module (20) is attached to the sensor unit for mounting the sensor unit (F) to the head adapter (16). The sensor unit (F) is to be mounted above an ocular axis (22) formed between a pair of eyes (24) of the user (U) when the sensor unit (F) is attached to the head adapter element (16). When the sensor unit (F) is secured to the user (U) with the head adapter element (16), the sensor axis (14) is essentially perpendicular to the user's ocular axis (22).
摘要:
The present invention comprises a method for detecting photons and generating a representation of an image. A photocathode receives photons from an image. A power supply to the photocathode is gated such that the photocathode is switched between an on state and an off state. The photocathode discharges electrons in response to the received photons while the photocathode is in the on state. A microchannel plate is located no more than about 125 microns from the photocathode. The microchannel plate has an unfilmed input face and an output face that receives the electrons from the photocathode. The microchannel plate produces secondary emission electrons which are emitted from the output face. A screen receives the secondary electrons and displays a representation of the image.
