摘要： A high resolution radiation sensitive imager includes a radiation sensitive photoconductive target for forming an image in response to incident radiation, a light sensitive cathode arranged in spaced apart relationship with the target, and an addressable light source coupled to the photocathode for causing the photocathode to emit electrons at localized sites for reading an image on the target.

摘要： A device for directly displaying X-ray images on a phosphor screen of a cathode ray tube by means of a steady cathodoluminescence is arranged such that the excitation of the phosphor screen is controlled by the persistent polarization and depolarization of the phosphor crystals in the phosphor screen by exposure to X-rays. The X-ray images formed on the phosphor screen in the cathode ray tube may be read out by synchronously detecting changes in the electric current of the collecting electrodes of the tube during the scanning of a reading electron beam on the phosphor screen displaying the X-ray images.

摘要： A programmable optical sensor is formed by coupling a proximity focused channel intensifier tube to a silicon target vidicon. The photocathode is gated by a first time programmed voltage and the gain of the microchannel plate is also controlled by a second time programmed voltage. The second voltage is less than 1,000 volts permitting the use of solid state circuitry.

摘要： This invention relates to such electron image devices as television camera tubes and image intensifier tubes and includes in one illustrative embodiment an electrically conductive member upon which there is disposed a first layer or region of a secondary emissive material deposited in a porous form to allow conduction of the secondary electrons through the voids of the porous material, and a second layer or region of greater density than the first layer disposed upon the first region to inhibit the escape of the secondary electrons emitted within the volume of the first layer.
