Abstract: The invention relates to an article comprising a length of an optical fibre and a package, the optical fibre comprising a fibre Bragg grating dispersed over a FBG-section of the length of the optical fibre, the package comprising a carrier with a carrier surface for supporting at least a supported part of the optical fibre including the FBG-section. The invention further relates to an apparatus comprising the article, to its use and to a method of manufacturing such an article. The object of the present invention is to seek to provide an optimized (e.g. elongate) package having a relatively low sensitivity to mechanical vibrations from the environment. This is achieved by providing that the carrier surface for supporting the optical fibre comprising a fibre Bragg grating is convex in a longitudinal direction of the optical fibre during use of the article.

Abstract: A lighting fixture projects a light beam for spot lighting in theater stages, cinema and television studios and the like. The fixture includes a light source at one end of a housing having a light beam exit aperture at the opposite end thereof, the light source and aperture being arranged generally concentric with a longitudinal or optical axis of the lighting fixture. One or more beam-shaping blades, and preferably also other light beam influencing elements, such as one or more lenses, an iris, and/or a pattern or gobo, are arranged along the path of the light beam along the longitudinal axis through the housing from the light source to the aperture. The position of the beam-shaping blade or blades, and preferably of all the light beam influencing elements, is adjustable relative to the longitudinal axis. The fixture produces a well-defined light beam or light cone with a geometry, angle of conicity and focal point that may be altered manually or by remote control.

Abstract: An image scanner in which an original is scanned by a trilinear CCD array, i.e. the original is scanned line by line, three lines at the time, one line for each color. Thus, at a specific time “only” the area of the original that is scanned by the trilinear CCD array at that time has to be positioned in focus of the imaging means of the image scanner while the remaining part of the original may be positioned anywhere and may adopt any suitable form. Thus, there is no need for all parts of the original to be kept flat and planar as required in known flat bed scanners. The original is kept flat and straight along a line to be scanned by imparting a substantially cylindrical shape, such as a circular cylindrical shape, to at least part of the original. The original is scanned along lines that are substantially parallel to the generatrix of the cylindrical part of the original.
