Abstract: An image intensifier is provided in which a thin film (090) is arranged between an output surface of the electron multiplier (040) and the phosphorous screen. The thin film is a semi-conductor or insulator with a crystalline structure comprising a band gap equal or larger than 1eV, wherein the crystalline structure has a carrier diffusion length equal or larger than 50% of the thickness of the thin film. In addition, the thin film has an anode directed surface which has a negative electron affinity. By way of provisioning a thin film of the above type in the image intensifier, an improvement in mean transfer function of the overall image intensifier is obtained.

Abstract: An X-ray imaging apparatus includes a top transparent conductive layer and a bottom transparent conductive layer electrically connected to the top transparent conductive layer. The apparatus also includes an X-ray field modulator positioned adjacent to the bottom transparent conductive layer and an electro-optic layer positioned between the X-ray field modulator and the top transparent conductive layer. The X-ray field modulator is configured to modulate one of a resistance and a charge level therethrough when exposed to different X-ray levels to thereby create different levels of voltage drop across the electro-optic layer. In addition, the different levels of voltage drop causes varying optical properties to appear in the electro-optic layer.

Abstract: An image sensor cell (100) is presented for use in an imaging device, for example of a night vision type. The image sensor cell (100) comprises an electrodes' assembly and a control unit (118). The electrodes' assembly is configured and operable to receive an input light signal and produce a corresponding electrical signal. The electrodes' assembly comprises a photocathode (112) having an active region capable of emitting electrons in response to incident light; and at least one electrode (114, 116) in a path of electrons emitted from the photocathode (112). The control unit (118) is configured and operable for controlling an electric field profile in said path so as to selectively cause the electrons' capture on said at least one electrode (114,116) resulting in accumulation of charge on said at least one electrode (114,116) corresponding to the input electromagnetic signal indicative of an acquired image, thereby enabling direct reading of the accumulated charge. The image sensor cell (100) thus provides for direct conversion of a light signal into an electric signal indicative thereof.

Abstract: An X-ray image intensifier (1) comprises an entrance screen (2) with a photocathode (3). A television camera (15) is optically coupled to the exit window (12) of the X-ray image intensifier. The X-ray image intensifier with the television camera derives a primary image signal from an X-ray image on the entrance screen. The X-ray image intensifier is provided with a radiation source (4), such as flashlights or LEDs, for irradiating the photocathode (3). Irradiation of the photocathode produces a light intensity distribution on the exit window wherefrom the television camera derives a control signal. Correction numbers are derived from the signal levels of the control signal. These correction numbers are employed for correcting the primary image signal.

Abstract: The contrast ratio of an image intensifier of the photocathode-amplifier-phosphor type is increased by using a fiber optic plate (23) of which the thickness is reduced to such extent that the plate may not be able to function as a vacuum seal or an electrical insulator when a typical voltage for the operation of the intensifier is applied to the phosphor layer (22). This relatively thin fiber optic plate (23) is placed entirely inside a vacuum, protected from the atmospheric pressure by a thick output window plate (25) which is optically transparent.

Abstract: A mounting system for night vision tubes includes a multi-part sleeve that opens in the manner of a clamshell to receive the tube. The sleeve includes a longitudinal seam or a partial longitudinal seam and opens around compliant hinge regions. The night vision tube engages a ramp section of the sleeve, urging the sleeve to open and then abuts against a front shoulder, causing the sleeve to clamp shut around the night vision tube. The tube is constrained between the front shoulder and a retaining shoulder. An indexing pin engages the night vision tube and the sleeve to maintain mutual rotational alignment. The sleeve and the tube are inserted into a housing of a night vision system.
