    Abstract: System to control the form of a charged particle beam. The particle beam emanates from a source (58) of these particles. This source is associated with a collecting electrode which collects the particles. The system comprises at least one resistive zone (56) and at least two control electrodes (52, 54), this resistive zone and these control electrodes being arranged substantially at the same level as the source, these control electrodes being furthermore placed on either side of the resistive zone and intended for polarising the latter, the electrical resistance profile of the resistive zone being chosen so as to have the distribution of potential making it possible to obtain the desired form of the beam emanating from the source when the control electrodes are suitably polarised. Application to the focusing of a charged particle beam.

    Abstract: The source comprises a series of electrodes (5) acting as cathodic conductors and carrying micropoints (12) and a series of electrodes (10g) acting as grids, each of the electrodes of one of the series being in contact with a resistive layer (7) and possessing a lattice structure, thereby including tracks (5a) which cross over and delimit first openings (6), each of the electrodes of the other series including second openings (11) offset with respect to the first ones.

    Abstract: A lighting device for liquid crystal display provides as output a polarized extended light flux. It comprises a light source 100 comprising a layer with high albedo A on the light emission surface SD(A), on which are stacked a quarter-wave plate 101 and a reflecting polarizer 103. This results in a light transmission gain of the order of 1+A, which makes it possible to produce displays with high luminance and low electrical consumption. Application to flat-screen displays.

    Abstract: The device has a measuring objective (2) to form an image from an optical Fourier transform of an elementary surface of an object in a Fourier image focal plane. A transfer unit (10, 12) forms the image on a CCD camera (14). A calculating unit (26) produces data concerning dimensional and/or structural characteristics of the object or identifies the characteristics from information provided by the camera. An independent claim is also included for a method to measure dimensional and/or structural characteristics of an object.
