    Abstract: An evacuated envelope has a rectangular display section and a gun section at one edge of the display section. The display section includes front and back walls which are generally rectangular, in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes therein gun structure which will direct electrons into the channels. In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel. The beam guide also includes means for selectively deflecting the electron beam out of the guide at selective points along the guide so that beam will impinge upon a phosphor screen along the inner surface of the front wall. In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen.

    Abstract: An evacuated envelope includes spaced, substantially parallel front and back walls, and a plurality of spaced, parallel supports between the front and back walls and forming a plurality of channels. A gun structure at one end of the channels directs at least one beam of electrons along each channel. In each of the channels is at least one beam focusing guide which confines the electrons in the beams but allows the beam to be selectively deflected out of the guide toward a phosphor screen on the inner surface of the front wall. Each of the focusing guides includes spaced walls between which the electron beam passes. Between the gun structure and each of the focusing guides is a beam clean-up section. The beam clean-up section serves to remove from the beam those electrons whose position and velocity vector are such that they would impinge on a wall of its focusing guide during the travel of the electron along the guide.

    Abstract: A foveated electronic camera employing a spatial-frequency spectrum analyzer and data-reduction means utilizing movable spatial windows for converting a high-resolution, wide field-of-view image into a group of subspectrum band images ranging in resolution and field of view from a lowest-resolution image of the entire field of view to a highest-resolution image of a selectably positionable smallest spatial subregion of the entire field of view. Such a camera is useful in a surveillance camera system and in a robotic system, by way of examples.

    Abstract: An evacuated envelope has spaced, substantially parallel flat front and back walls. Along the front wall is a phosphor screen and along the back wall are electron beam guides for guiding beams of electrons along paths substantially parallel to the front wall. The beam guide includes a pair of spaced, parallel plates between which the beams pass and a plurality of aligned openings in the plates with the openings being arranged in rows extending along the paths of the beams. A gun structure which includes at least one cathode is provided at one end of the beam guide plates. The gun structure is adapted to generate the electrons and direct the electrons as beams between the beam guide plates. The beam guide plates have tabs extending from the one end toward the cathode with the tabs being positioned at the ends of the rows of the openings in the plates. The tabs are adapted to generate electrostatic fields which guide the beams from the cathode between the plates along the rows of the openings.
