  • Apparatus for the element-wise reconstruction of a tomogram of a cross-section of an object
    Patent number: 4209827
    Abstract: A system for reconstructing a tomogram or a portion thereof of a cross-section of an object. Modified signal profile data obtained by exposing the object to a substantially flat beam of penetrating radiation from different angles and by preprocessing the transmission radiation received at positions respectively corresponding to the different angles of incident radiation is stored in an analogue form into a collection of primary record paths, each of which is uniquely related to an associated angle of incident radiation; whereas such information elements stored in various of said primary record paths as are included in a secondary path that is uniquely defined by position coordinates determinative of the radiation absorption or density of a certain element of the object cross-section, are integrated.

  • Planar multiple switch
    Patent number: 4207444
    Abstract: The frequency capability of a planar multiple switch for entry of digital data is improved by forming an upper conductive planar member from fine conductive elements electrically joined, such as a screen or conductor pattern, together but with sufficient space between elements to substantially reduce capacitive coupling between the upper member and lower contact members. Further, multiple bit switch areas are formed adjacent single bit switch areas; and coded contact areas are formed on parallel lines by placing insulation on selected sections of lines and building up adjacent contact sections by additional conductor material.

  • Synthetic aperture scanner for decoding a coded image produced by penetrating radiation, such as X-rays
    Patent number: 4191890
    Abstract: A system for decoding a coded aperture image of an object exposed to short-wave radiation from a plurality of point sources positioned in space in accordance with a given distribution. The coded aperture image is displayed by a cathode ray tube having its screen optically coupled to the entrance screen of an image intensifier tube. This image intensifier tube is effective to consecutively shift its entrance screen image in its entirety along a field pattern of lines. The images thus produced on the exit screen of the intensifier tube are transferred through a mask system having a transparency pattern related to the distribution pattern of said point sources, to a detector which position wise integrates the light transmitted through said mask system.
