摘要:
A fiber optic viewing device has in a first embodiment, a color-preserving image intensifier positioned at the viewing end thereof. In a second embodiment, an input light source is sequentially modulated through a cycle of wavelength sets. The resulting image is intensified and recolored by an output recoloring filter which is synchronized with the input light modulation. In yet another embodiment, a set of red, green and blue LEDs are sequentially modulated by a controller to provide input light. A CCD camera receives the resultant intensified image and converts it to video format. A video processor stores frames during a cycle of modulation and then integrates the frames for viewing in full color.
摘要:
A method for annealing a deposited material on a substrate structure, where the annealing temperature of the deposited material is greater than the melting temperature of the substrate structure, including the step of inserting the substrate structure into an oven preheated to a temperature above the annealing temperature. The substrate structure is kept in the oven for a time interval wherein the mean temperature of the deposited material is above the annealing temperature and the mean temperature of the substrate structure is below its melting temperature. The substrate structure may be actively cooled while in the oven, thus increasing the time interval the mean temperature of the deposited material can be maintained above the annealing temperature.

An image display device having an image transmissive faceplate with an exterior surface spaced from a light filtering layer of uniform thickness on a protective transparent panel by an encircling sealed gasket to form an interposed cavity which is filled with image transmissive bonding material. A method comprising the steps of (1) casting an annular gasket in encircling sealed relationship with an implosion panel, (2) depositing within the annular gasket and on the encircled panel a uniform thickness layer of light-filtering material, (3) sealing the gasket to an outer marginal portion of a display tube faceplate to form a cavity between the faceplate and the layer of light-filtering material on the implosion panel, and (4) filling the cavity with light transmissive bonding material.
摘要:
The present invention is a vacuum housing for an image intensifier tube, wherein the vacuum housing is unistructurally formed from a dielectric material and retains a photocathode, microchannel plate (MCP) and anode within an evacuated environment. The vacuum housing is manufactured as a single, solid component, thereby having no seams which may leak and compromise the evacuated environment. The various electrically operative elements of the photocathode, MCP and anode engage separate metalized surfaces formed within the vacuum housing. The electrically operative elements of the photocathode, MCP and anode within the vacuum housing are empowered by coupling the various metalized regions to sources of electrical potential external for the evacuated environment.
