Abstract: A method and a device for tuning a Bragg grating in an optical fiber is disclosed. Tuning of the grating is obtained by applying current to at least one longitudinal, internal electrode arranged along the core of the fiber. When current is passed through the electrode, thermal expansion occurs that produces a stress on the fiber core. At the same time, the temperature of the core is increased. This leads to an electrically controlled tuning of the Bragg grating.

Abstract: A method of forming a longitudinal solid body within at least one longitudinal hole formed in an optical fiber, comprising the steps of placing a first end and a portion of the optical fiber ina heating chamber; keeping a second end of said optical fiber outside of the heating chamber; forcing a molten material into the longitudinal hole of the fiber from the first end; and thereupon longitudinally extrancting the optical fiber from the heating chamber at a controlled rate. Preferably, the fiber is extracted while molten material is being urged into said fiber.

Abstract: The invention relates to a method and a device for controlling the refractive index in the core of an optical fiber. According to the invention, an optical fiber is provided with a longitudinal electrode running along the core of the fiber. An electric current is passed through the electrode to induce ohmic heating thereof, causing thermal expansion and consequently a compressing force upon the core of the fiber. This compression of the core leads to induced changes in the refractive index in the direction of the compressing force, and hence induces or alters birefringence in the core.

Abstract: A method of repairing a vehicle chassis and/or vehicle bodywork which requires the replacement of a damaged vehicle part with a new vehicle part. The vehicle is clamped to a working bench and the new vehicle part (4), which is to be welded in position for instance, is held firmly in a correct position in relation to the vehicle (1) with the aid of bench-coacting holding devices (5, 18). The bench-coacting holding devices (5, 18) include positionally adjustable means (10, 11, 13) which are intended to coact with specific points of the new vehicle part, the positions of these points in space relative to the vehicle being known. In this regard, the positions in space of the positionally adjustable means are set with the aid of separate measuring equipment. The invention also relates to an arrangement for use when carrying out the method.
