Abstract: The invention is directed to electrostatic deflection systems for corpuscular beams which can be used particularly in microstructured and nanostructured applications in lithography installations or measuring equipment. According to the proposed object of the invention, the individual electrodes of a deflection system of this kind should permanently have and retain a very exact axially symmetric arrangement relative to one another. In the electrostatic deflection system according to the invention, rod-shaped electrodes are held in an axially symmetric arrangement in an inwardly hollow carrier through which a corpuscular beam can be directed. The carrier is formed of at least two, and at most four, carrier members which are connected to one another.

Abstract: A method for the evaluation of radar data for fully automatic creation of a map of regions with interference, in which undesirable reflections frequently occur includes the following method steps. The region to be mapped is divided up into cells. The short-lived target tracks that occur in these cells are counted. Statistics are kept, in such a manner that the short-lived target tracks are counted only within a predetermined period of time, while all older short-lived target tracks are left out of consideration. At least one threshold value is predetermined, in such a manner that a cell is considered to have been marked if the short-lived target tracks that are counted in the previous time period exceed the threshold value or values. The map of the current regions with interference results as the totality of the marked cells.

Abstract: In a method of marking faults on rapidly moving material webs the material web is moved past a fault detection scanning device, which cyclically scans the web transverse to its longitudinal direction, and past a marking device at a defined distance therefrom. Signals coming from the fault detection scanning device (16) are analyzed one after the other to determine whether they are fault signals or structure signals. The fault signals which are detected are stored with their web coordinates. Checks are made at short time intervals as to whether a fault signal is present in the store (11) which corresponds to the longitudinal coordinate which is just moving past the marking device (13). A marking is effected if a fault signal is present at the corresponding web coordinates (FIG. 1).

Abstract: A fault detecting apparatus for flat articles generates a line of light on the article which is imaged onto a photoreceiver via an optical system having cylindrical imaging characteristics. For use with an article 11 having light diffracting characteristics the line of light 12 is arranged substantially at right angles to the structure 13 which causes the light diffraction. The optical system 14 having cylindrical imaging characteristics detects, apart from the zero order at least also the first diffraction order of the light leaving the article. The light of the first diffraction order is also imaged onto its own photoreceiver (FIG. 1).

Abstract: In an optical fault seeking apparatus for webs moved in their longitudinal direction there is provided an optical scanning arrangement which generates a light bead on the surface of the web which moves transversely to the direction of the movement of the web. The scanning arrangement generates several light traces (12, 13, 14) which are displaced in the direction of advance and are parallel to one another. A light receiving arrangement (15) for each light trace has a photoelectric receiver (16, 19; 17, 20; 18, 21). The light traces (12, 13, 14) either adjoin one another or have a distance such that after the passage of the web (22) past all the light traces (12, 13, 14) each web region has been detected once by one scanning light bead (FIG. 1).
