摘要： A Multichannel Fiber Optic Rotary Joint (FORJ) has a Dove prism as a derotating optical element, wherein the Dove prism has a multiwavelength achromatic metasurface coating on the input and output face. Such a Multichannel FORJ has the advantage that its transmission properties include consistently low attenuation over a rotation angle and a high-return loss over a broad wavelength range, e.g. the whole frequency band used for telecommunications. A method for fabricating the same.

摘要： A method for compensation of input voltage fluctuations in an inductive rotating coupler is disclosed. This coupler includes a power generator that feeds an alternating-current voltage into a resonance circuit including a resonance capacitor and an inductive rotating transmission device. The power generator is fed with an input direct-current voltage that may fluctuate, for example, owing to residual ripple. A control unit determines this input direct-current voltage and calculates there from an optimum operating frequency for the power generator, so that the output voltage at the load remains constant.

摘要： A slip ring assembly for the electrical connection of two rotating parts has at least a sliding track with V-grooves. At least two brushes of electrically conductive material are contacting the sliding track within the V-groove. The brushes are connected electrically with each other and mounted at different levels resulting in a different distance to the rotation axis of the sliding track. This results in an improved resistance against shock and vibrations.

摘要： A slip ring device for the electrical connection of two mutually rotatable parts includes one or more slideways each with at least one V-groove. At least two wire brushes are provided which run in (are configured to extend into) the V-grooves. The wire brushes are electrically connected to each other and are mounted on at least two different brush blocks which are mechanically decoupled from one another. Increased insensitivity to vibrations and mechanical impacts can be achieved in this way.

摘要： A method is disclosed for compensation of system tolerances in an inductive coupler which includes a power generator that feeds an alternating current into a series resonance circuit formed by a resonance capacitor and an inductive rotating transmission device. First, a brief sequence of at least one period of an alternating current is fed by the power generator into the series resonance circuit. Then the series resonance circuit is short-circuited. A first resonance frequency is measured. Then a longer sequence having a plurality of periods of an alternating-current voltage is generated by the power generator, so that a given small voltage is built up at the load. Now a second resonance frequency is measured while the resonance circuit is short-circuited. Then at least one correcting variable for the power generator is determined from the two resonance frequencies.

摘要： A collimator system comprises a micro lens array and a fiber array. The fiber array has a substrate with a plurality of holes for holding a plurality of optical fibers. The fibers are glued into the holes. Before gluing, each of the fibers is positioned against the same side of a corresponding hole resulting in all fibers being located substantially equally with respect to the holes. The lens array is mounted with an offset to the fiber array resulting in alignment of the fibers and the lenses.

摘要： A fiber optic rotary joint has at least one fiber optic collimator. The fiber optic collimator has a plurality of lenses on a micro lens array. Furthermore a plurality of optical fibers are attached to the micro lens array. The fibers are further fixed by a fiber support. A spacer is provided between the micro lens array and the fiber support, setting the micro lens array and the fiber support apart from each other. The optical fibers have between the micro lens array and the fiber support a excess length greater than the distance between the micro lens array and the fiber support. This results in a slight bending of the fibers between the micro lens array and the fiber support. A temperature related extension of parts of the fiber optic rotary joint can be compensated by the excess length and does not lead to mechanical tension on the fibers.
