摘要： An optical fiber sensor has a measurement path and a reference path. Both paths each consist of two optical fibers and are fed with modulated light. The fibers of the reference path have a predefined difference in length, whereas the fibers of the measurement path are the same length. All fibers are at approximately the same temperature. An evaluation circuit determines the phase differences in each case between the fibers of the measurement path and of the reference path. A measurement value calculated from the phase differences is then output.

摘要： The invention relates to a device for determining the position of a signal source configured to emit signals modulated by a modulation frequency, comprising: a conductor arranged in such a way that it receives the modulated signals at various positions along the conductor and configured to conduct the modulated signal, respectively in opposite directions, to a first conductor end and to a second conductor end when a modulated signal is received; a detector configured to acquire the modulated signal at the first conductor end and at the second conductor end; and a determination apparatus configured to: determine a phase difference between the modulated signal acquired at the first conductor end and the modulated signal acquired at the second conductor end, and determine the position of the signal source in relation to the conductor on the basis of the phase difference.
