    摘要: A multichannel integrated optics modulator is disclosed that generates one or more independently modulated scanning beams. The integrated optics modulator includes at least one waveguide channel provided on an electro-optic substrate, wherein the waveguide channel is divided into a write waveguide channel that extends to an output side of the substrate and a dead-end waveguide channel that terminates before reaching the output side of the substrate. Control signals are selectively applied to electrodes provided above the dead-end waveguide channel and the write waveguide channel to control the coupling of light from the write waveguide channel to the dead-end waveguide channel. Light is coupled out of the dead-end waveguide channel through the use of an absorber located above an end region of the dead-end channel. The integrated optics modulator is incorporated in a variety of scanner mechanisms.

    摘要: Un appareil d'exploration optique comprend une source de rayonnement cohérent ou essentiellement cohérent, un hologone radial, une lentille f et une cible. Entre la source lumineuse et l'hologone, on place des moyens destinés à transformer le rayonnement provenant de la source en un faisceau aligné ayant une section oblongue et à diriger le faisceau sur l'hologone selon un angle d'incidence prédéterminé et avec l'axe longitudinal de la section transversale oblongue du faisceau radial par rapport à l'axe de rotation de l'hologone. Deux prismes (56, 58) sont placés entre l'hologone et la lentille, afin de modifier la forme à section transversale oblongue du faisceau (169, 191), de telle sorte que le point d'incidence du faisceau sur la cible présente une forme et une orientation sélectionnées. Les prismes sont montés dans une structure articulée (101) pourvue d'un moyen de réglage (143), qui permet la rotation des prismes de façon à corriger à la fois l'arc de la ligne d'exploration et le placement incorrect de la ligne d'exploration sur la cible. L'origine dudit arc et dudit placement incorrect pourrait être une modification de la longueur d'onde de rayonnement et un écart des lignes de quadrillage de l'hologone différent de la valeur nominale.
