1. A localization system comprisingan electromagnetic wave source for splitting an electromagnetic signal into components and propagating the components along at least one probe path and along a reference path;

  • a signal outlet attached to an end of the at least one probe path for emitting the electromagnetic signal component propagating the probe path, the end is positioned at a point of interest;

    a detector for picking up the emitted electromagnetic signal component from the signal outlet;

    a correlator for correlating the electromagnetic signal components propagated long the probe path and the reference path; and

    an evaluation unit for estimating a spatial location of the signal outlet relative to the detector based on the correlation.
