Abstract: Method and means for creating an interaction between a beam of particles and electromagnetic waves, particularly at optical frequencies, wherein a high velocity beam of particles, such as electrons, is passed through a suitable interaction zone, for example, in the form of an optically transparent dielectric target, such as a thin crystalline film, while the target is irradiated with laser light polarized generally in the direction of travel of the particles, whereby the particles upon striking a suitable medium, such as a non-luminescent screen, give off light of the same color as the laser, which becomes visible on the screen. The interaction thus derived can be used in many particular applications such as, for example, in a color television tube and other electronic display or information storage devices.

Abstract: Disclosed is a fiber optic image storage device of the type having a plurality of light-conducting optical fibers secured together in side-by-side relation so that corresponding opposite ends of the fibers cooperate to define first and second faces. Each of the fibers is characterized in that it comprises a glass core and a layer of photochromic glass formed upon the surface of the core. The layer of photochromic glass may function as a sheath having a refractive index substantially the same as that of the core, or it may have a refractive index lower than that of the core thereby forming with the core a light reflecting interface. The core may consist of a photochromic glass or a nonabsorbing glass.

Abstract: This invention provides a high resolution direct view storage tube which, in addition to having superior resolution capabilities, also requires less complex circuitry than standard type direct view storage tubes. More particularly, a meshless storage tube is disclosed which makes use of a meshless multilayered thin film structure as a combined image storage and display medium. The principle components of this structure include a thin film electronic storage medium, an opaque antifeedback layer, and an electroluminescent image display layer. In operation, a bias voltage is maintained across the entire structure, and a high resolution image is initially impressed upon the storage medium by means of a scanning electron beam. The scanning beam creates local conductivity modulations within the storage film which correspond to the input image, and these modulations, in turn, alter local field configurations across the electroluminescent layer, thus creating a visible output image. After initial scanning, the conductivity modulations in the storage layer are maintained for an extended period of time (several tens of seconds) provided that an applied electric field continues to be maintained. This phenomenon is hereinafter referred to as ''''field sustained conductivity.'''' Removal or reversal of the applied electrical field restores the storage element to its initial insulating condition, and the screen is thereby erased.

Abstract: Deformation of a gate by Coulomb force generated when operating an electron-emitting device is inhibited by appropriately maintaining relationship between film thickness h of the gate and distance L from an outer surface of an insulating member to an inner surface of a concave portion. According to this, in an electron beam apparatus provided with a laminate-type electron-emitting device, the deformation of the gate is prevented to reduce variation in electron emission characteristics, thereby preventing the element from being broken.

Abstract: A Laser-CRT is described in which the laser faceplate is at high potential and the cathode is above ground. The cathodes can be modulated in a dual-drive or push-pull mode in which each of the dual video amplifiers is required to swing only half of the total required voltage, thereby writing smaller pixels faster and achieving higher resolution. Another described embodiment provides a substantially constant laser output over time, and an approximately uniform output intensity over an area. A constant-output Laser-CRT can be used to illuminate a spatial light modulator (SLM) in a projection system, and since video modulation is not required in that embodiment, neither are costly electronics and merely a voltage bias need be applied to the electron gun (e.g., the K electrode) to turn on the electron beam.
