Patent ID: 7708226

Claim:
A device for detecting synchronous errors of high-lift surfaces ( 2 ), comprising an optical conductor ( 5 ) which is laid over at least two adjacent high-lift surfaces ( 2 ), a light source ( 6 ) and an optical receiver ( 7 ) which are allocated to different ends of the optical conductor ( 5 ), as well as an evaluation unit ( 8 ) for determining a synchronous error of the high-lift surfaces ( 2 ) on the basis of the light signal received from the optical receiver ( 7 ), wherein the optical conductor ( 5 ) is placed in such a way that the optical conductor ( 5 ) experiences a break-free deformation due to synchronous errors and consequently causes a change of the transmitted light signals, and that the evaluation unit ( 8 ) compares the signal shape of the light signal received from the optical receiver ( 7 ) or an optical receiver output signal derived therefrom with a nominal signal shape and determines the presence of a synchronous error on the basis of the deviation in shape between the received light signal or the optical receiver output signal derived therefrom and the nominal signal.
