An arrangement of at least three magnetic dipoles is respectively arranged on both rings, the magnetic dipoles facilitating magnetic coupling of the rings and a transmission of torque from a driving ring to a driven ring of the two rings. The magnetic dipoles of the arrangements at the driven ring and/or at the driving ring is/are aligned such that two like magnetic poles, which adjoin one another on the respective other ring, are always followed by an unlike magnetic pole, and the magnetic poles adjoining one another at the respective other ring are arranged in a manner corresponding to one another such that the two rings are magnetically coupled in an equilibrium position.

Abstract: A high-frequency transmission of data between functional units, which are mounted rotatably with respect to each other, of an endoscope, is permitted in which the functional units can be electrically insulated from each other. For this, an electric connecting element which, in a central flexible portion, is rolled up transversely with respect to the direction of transmission and is fastened by its respective end portions to the functional units is provided. An uninterrupted electrical connection with consistent quality of the signal transmission can therefore be obtained even when the functional units are rotated in relation to each other. By the rolling up of the central portion to form a winding, which is preferably configured in a self-supporting manner, a long term stable rotary degree of freedom is created in a very simple manner for the connecting element, with this degree of freedom permitting complex mechanical adjustment functions in the endoscope.

Abstract: For an imaging method for presenting fluorophores (5) by optical excitation, spontaneous emission of fluorescence and detection of same, a single, conventional sensor (6) is used having at least two color channels, which detect an excitation light used to excite the fluorophore (5) and the fluorescence emitted by the fluorophore (5) with different sensitivities. Due to the different spectral distribution of the sensitivity of the color channels, it is possible to separate the component of the excitation light from the component of the fluorescence, in particular in a specific pixel, from one another by processing output signals of said color channels, in particular by conversion into a color space and/or by calculation of color saturation values. From this, the intensity of the fluorescence can be deduced, preferably taking account of a relative luminance measured by the color channels, even though reflected excitation light reaches the color channels, in particular in an unfiltered manner.
