Abstract: A test image projector operating in the ultraviolet through infrared specm that is comprised of two symmetrically mounted identical mirrors which are off-axis sections of an astronomical quality parabola. The first mirror produces collimated beams from object points and reflects these collimated beams onto the second mirror while the second mirror refocuses the collimated beams into diffraction limited image points, and thus provides a diffraction limited test image. The test image is used to check the quality of optical and electrooptical systems.

Abstract: A column of infrared detectors are repetitively optically scanned across an nfrared scene. The outputs of the detectors are fed to a viewing matrix of light emitters consisting of a plurality of columns of detectors, each column having light emitters corresponding to respective detectors. As the detectors are scanned across the scene, successive columns of detectors are energized or enabled such that the light emitted by the individual emitters is directly related to the infrared radiation falling on a corresponding detector. The image may thus be directly viewed by an observer. An alternate system employs a storage matrix having light detectors corresponding to the emitters of the viewing matrix such that the output of the viewing matrix, instead of being directly viewed, is stored and is then read out in a normal television raster to provide a video signal for distant television viewing.

Abstract: Minature video-type display comprised of an otherwise normal microchannel ate (MCP) image intensifier wafer tube which uses, instead of the normal input faceplate having a uniform photocathode, a video-driven one-dimensional electroluminescent array on the output surface thereof and an orthogonal one-dimensional photocathode array mounted on the inner surface thereof. The fiber optic faceplate contains vacuum feed-throughs for the cathode array elements.

Abstract: A miniature flat panel image intensifier display tube having an array of ctrically isolated parallel photocathode array stripes adjacent and orthogonal to a microchannel plate input electrode array comprising electrically isolated parallel metallic stripes. A video picture signal generator modulates a radiation source that causes a generally uniform flow of photons to impinge on the photocathode array. The photoelectrons that are emitted from the photocathode array are selectively accelerated into a charge pattern according to differential voltages scanned across both arrays by array switching electronic means wherein the charge pattern is converted to a visible image for viewing by an observer.

Abstract: A toric reflector display comprising a toric concave reflector with a toric onvex object surface, an auxiliary display device, and an optical transfer device which transfers information from the auxiliary display to the toric object surface. The toric reflector display provides an observer with a distant virtual image of the information. The virtual image of the information may be viewed superimposed on the real world if the toric concave reflector is semi-opaque.

Abstract: A picture element array image intensifier tube display device and system providing image analysis and processing schemes for an image in either direct or remote view. The picture element array comprises an array of electrically isolated parallel photocathode stripes that are adjacent and orthogonal to a microchannel plate input electrode array of electrically isolated parallel metallic stripes which have differential bias voltages selectively switched thereacross in some selective scan mode wherein said bias voltages are varied according to image analysis and processing schemes in a feedback circuit.

Abstract: A picture element array image intensifier tube display device and system providing image analysis and processing schemes for an image in either direct or remote view. The picture element array comprises two in-line microchannel plate (MCP) electron multipliers having an array of electrically isolated parallel output electrode stripes on a first MCP that are adjacent and orthogonal to a second MCP input electrode array of electrically isolated parallel metallic stripes. The input and output electrode array stripes have differential bias voltages selectively switched thereacross in some selective scan mode wherein said bias voltages are varied according to image analysis and processing schemes in a feedback circuit.

Abstract: A miniature flat panel image intensifier tube display device using two inne microchannel plate (MCP) electron multipliers that have two arrays of orthogonally positioned electrically isolated parallel metallic stripes as electrodes on their interfacing surfaces and have the conventional continuous electrodes on the other two surfaces. A solid photocathode layer is in proximity focus with the solid input electrode of the first MCP, and the solid output electrode of the second MCP is in proximity focus with a display device. Array switching electronic means selectively switches bias voltages in some selected scan mode over the two arrays of MCP metallic stripes to provide a selective electron charge pattern exiting the second MCP wherein the charge pattern is converted to a visible image at the display device.
