Abstract: Rapidly varying light phenomena are observed by scanning on a screen the image of a slit in a photocathode which collects the light coming from the phenomenon to be studied. The image converter tube comprises separate electronic means respectively for forming the image of the longest dimension of the slit on the screen and for focusing and deflecting the beam in the plane of the screen in a direction at right angles to the longest dimension of the slit.

Abstract: An electrostatic field shaping electrode is mounted external to an image intensifier tube in proximate spaced-apart aligned coaxial relation to an insulating envelope wall portion which is exposed to an internal electron accelerating cavity. The field shaping electrode may be employed during the operation of the tube for substantially preventing electron bombardment of the exposed insulating wall portion and for avoiding spurious output signals resulting from the generation of positive ions by that electron bombardment.

Abstract: Structures to be used during focalizing of an optical system which has a focal plane. A composite photoconductive assembly is situated at the region of the latter focal plane and includes a pair of photoconductive portions, a substrate common to and carrying these photoconductive portions, a light-diffuser situated in front of one of these photoconductive portions for diffusing light which reaches the same, and a light-transmitter situated in front of the other of the photoconductive portions for transmitting non-diffused light thereto. In this way these photoconductive portions generate separate photoelectric outputs in response to diffused and non-diffused light respectively impinging on the above photoconductive portions. An electrical structure is electrically connected with these photoconductive portions for comparing the outputs thereof so as to detect from a comparison of these outputs the focal adjustment of the optical system.

Abstract: A flat large-area photocathode intended for use in an intensifier tube is constructed so that a pre-determined potential gradient can be maintained across its surface in operation in order to simplify the electron-optical system of the intensifier. This is done by providing photoemissive material on an electrically resistive layer or sheet on a major surface of which is provided a series of spaced rings of electrically conductive material one inside the other. The spacings and widths of the rings are chosen so that, when a potential difference is applied between the center and the edge of the sheet or layer, the desired potential gradient is set up across the surface of the photocathode. The intensifier tube may be an x-ray image intensifier.

Abstract: An electron-optical image tube is made capable of providing direct measurement of luminous events having durations as short as one picosecond and with a time resolution in the picosecond range by providing a metallic mesh extraction electrode in close proximity to the photo-cathode of the image tube and connecting this extraction electrode to a source of positive potential of variable voltage. An image tube streak camera incorporating such an image tube provides means whereby the photo-electrons in the image tube are deflected by a pulsed electric field of rapid rise time to produce a streaked record. The image tube is particularly suited for use in the analysis of laser beam pulses.
