Abstract: Flat panel image sensor (10) is provided by combining photoconductive imaging electrodes of a vidicon with a two-dimensional array of cold cathode field emitters (14) commonly used for flat panel field emission display (FED) systems. The FED operates normally to emit electrons which are accelerated in prior art displays towards a luminescent phosphor to generate light output proportional to the cathode emission. Rather than accelerating towards a phosphor, electrons are accelerated towards a photoconductor layer (16) to replace charge removed from the layer by an incident radiation pattern directed at the photoconductor layer (16) through a layer of transparent, electrically-conducting material (17) which serves as a radiation window. The transparent, electrically-conducting layer (17) may be partitioned to reduce stray capacitance for large area sensors and the partitioned, electrically-conducting layer (17) permits a parallel readout mode of operation.

Abstract: The present invention provides an enhanced THz electromagnetic source structure achieving a very high aspect ratio of 500 to 1 of electron beam width to electron beam thickness of the electron beam moving in the direction across the grating structure while maintaining its cross-section. The structure comprises a magnetic circuit providing a unique low magnetic field slot placed in a steel core for the placement of an electron gun, thus allowing the electron beam to he focused without the interaction of a magnetic field while still supporting a high magnetic field in the grating region. Additionally, the structure comprises an electrostatic shield preventing potential difference between the anode voltage and the grounded steel core from affecting the focusing of the electron beam.

Abstract: Apparatus and method are provided for a package structure that enables mounting of a field-emitting cathode into an electron gun. A non-conducting substrate has the cathode attached and the cathode is electrically connected to a pin through the substrate. Other pins are electrically connected to electrodes integral with the cathode. Three cathodes may be mounted on a die flag region to form an electron gun suitable for color CRTs. Accurate alignment of an emitter array to the apertures in the electron gun and other electrodes such as a focusing lens is achieved. The single package design may be used for many gun sizes. Assembly and attachment of the emitter array to the electron gun during construction of the gun can lower cost of construction.
