Definitions
- the invention relates to an optical distributor for distributing light, in particular laser light, between at least one optical input and at least one of a plurality of optical outputs.
- the present invention relates to an operating method for such an optical distributor.
- Optical distributors are known in the field of optical communications technology, in particular as so-called fiber-optic power dividers which divide radiation power from an input fiber onto a plurality of output fibers.
- fiber-optic power dividers which divide radiation power from an input fiber onto a plurality of output fibers.
- a disadvantage of such fiber-optic power dividers is in particular the fact that the radiation power supplied to the output fibers is usually orders of magnitude smaller than the radiation power present in the input fiber.
- distributed coupler structures are also known in which the radiation power is distributed from the input fiber to the output fibers over a more or less spatially extended area.
- coupler structures are also known from optical communications technology, for example, fiber ground couplers, fusion couplers and the like. All these known couplers or optical distributor have a relatively complicated structure, have correspondingly high manufacturing costs and are also unsuitable for use in the automotive sector or in other operating environments with particularly difficult environmental conditions such as vibration, high temperature fluctuations and the like.

- the inventively movably arranged light guide and provided for its movement actuator allow for a relatively low design effort flexible forwarding or distribution of light or general optical radiation power between one or more inputs and one or more outputs of the optical distributor.
- the optical distributor according to the invention is based largely on components which are correspondingly robust for use For example, in the automotive field can be designed and can be produced inexpensively and are low maintenance.
- optical distributor according to the invention is that due to the movably arranged optical waveguide for the distribution of the radiant power almost no transmission of radiant power takes place outside the optical waveguide or the optical inputs and outputs. Accordingly, the transmission of radiant power via "open light paths", such as air-filled areas between two fiber ends, is minimal, resulting overall in a very low-loss construction.
