The embodiments relate to a sensor strip () and to a flexible support strip () for receiving the sensor strip and for fixing the strip to a surface e.g. to the back of a test person. According to the embodiments, the sensor strip () has a reference point (), (for example a snap fastener connection), with which it can be fixed to a reference surface () of the support strip. This allows the position of the sensor strip () to be unambiguously defined on the support strip (). The further extension of the sensor strip () lies in a pocket () so that it can slide, allowing the relative movement between the support strip and the sensor strip if the support strip is lengthened (represented by a dot-dash line). The entire sensor unit is thus advantageously more comfortable to wear, as the elastic support strip (), for example, can freely follow the back movements of the test person.

In a method for the production of optical bands with several optical fibers, the surface of the optic fibers in said bands is treated such as to increase the optical damping in sections of the optic fibers. The generated damping may be reliably adjusted, whereby during (or after) the processing of the surfaces a measuring light is introduced into the fiber optic and the light output at the other end of the band is measured by means of a sensor such as a CCD camera. Possible production errors can thus be compensated for during the production process, for example, by an increased process time for the optic fiber. Optical sensor bands can be produced by the above method for application in the bumpers of motor vehicles as recognition sensors for the impact of a pedestrian. Other applications in which the bending of a sensor band is to be determined by optical means are also envisaged.

A rotary transmitter for transmitting optical signals between two components is described. In accordance with the invention, provision is made for a fiber optic cable, optionally also a second fiber optic cable to be used to transmit the signals, the latter being suited, due to their surface treatment, to coupling signals of send elements and forwarding them to an interface in order to be registered there by a receive element. The fiber optic cables are laid such that they describe a circle upon which the transmission elements rotate about an axis of rotation. As a result, a complete data transmission is possible by way of the waveguide. The components (send elements, receive elements and the optical fiber cables) can be fastened to an annular printed circuit board by SMT.
