Date Aug. 8, 1991.The invention relates to optical elements, particularly retro-reflecting, retro-imaging and optical transmission inversion elements to relay a true scale equal conjugate image of a scene. Hitherto, the image had a resolution limit set by the pitch and/or packing density of micro-optical elements to reflect or transmit ray bundles impinging on them, the number of elements within the viewing zone determining the lateral and hence depth resolution in any given direction. The object of the invention is to reduce the effect of micro-screen texture in a relatively inexpensive manner, that provides real-time systems and which can be used with fast moving objects. This objective is met by an optical element comprising a retro-reflecting or auto-collimating transmission screen (9) having one or more lenses (6,10) and an associated means (8,11) of displacing wavelengths to different degrees and whereby to spread a reflected or transmitted image into a spectral streak. The means (8,11) of displacing wavelengths may be a grating, mechanically or optically blazed, or formed from prisms, or may be a diffraction or zone plate.

Abstract: Un bloc (41) fixe un conduit (43) dans un canal (42) et positionne au moins un transducteur (50) de manière que des signaux acoustiques se déplacent le long d'un chemin précisément défini dans un fluide s'écoulant. Pour des petits tubes, deux transducteurs (72, 73) sont couplés à un tube et lançent des signaux d'interrogation acoustiques le long d'un chemin axial à l'intérieur du tube. Pour des conduits plus gros, deux transducteurs (420, 430) lancent des signaux obliques suivant un chemin en zig-zag dans le fluide, se réfléchissant sur une paroi intérieure du conduit. Un support de transducteur comprend une pluralité d'éléments massifs placés dans le chemin de propagation acoustique afin d'éliminer les interférences. Dans un mode de réalisation préféré, ces éléments sont des anneaux (10, 11), lesquels sont fixés à un cylindre épais ou usinés à partir de ce dernier, afin de laisser un cylindre à paroi mince (14) maintenant un transducteur (220) séparé de la paroi d'un conduit (4a). Selon un autre mode de réalisation, un tube à paroi épaisse (230) pourvu d'encoches orientées radialement (232) constitue la structure de support du transducteur.

Abstract: A process is described for the electrical and mechanical surface passivation of sensors, e.g. semiconductor sensors, using a vacuum installation comprising     a receiver with connections for gas inlet and gas outlet lines, an anode and a cathode above which a substrate holding device is disposed, for coating the sensor with a layer of material according to the CVD process by means of a plasma-supported layer deposition, and measuring and control devices for the process parameters determining the sputtering process, such as gas flow, pressure and the electrical power injected into the plasma.   In a first process step according to the invention, a filler gas is passed into the receiver, and a high frequency is applied to the electrodes for igniting a plasma within the receiver. The sensor surface is then cleaned by impurities being sputtered off from the sensor surface by means of plasma particles impinging on the sensor surface. In a further step, a silicon-containing monomer and an additional gas are passed into the receiver while the addition of the filler gas is continuously throttled and the plasma is maintained, the electronic characteristics of the electrical power injected into the plasma being registered at the same time. Finally, this results in the deposition of a compound of the silicon-containing monomer and the additional gas on the sensor surface.
