ABSTRACT:
In a fiber optic sensor for measuring electric fields and voltages, in place of a bimode fiber extending between sensor head (14) and evaluation unit (13) two separate bimode fibers (4a, 4b) of the same type are connected in series in the manner of a tandem interferometer. The first bimode fiber (4a) is disposed, together with the sensor element (6), in the sensor head (14). The second bimode fiber (4b) is situated within the separate evaluation unit (13). In this way, the sensor head (14) and the evaluation unit (13) are connected only by insensitive monomode fibers (2a, 2b).
