Abstract

A method for estimating a geometrical shape of an optical fiber (106) includes transmitting (102) into the optical fiber an input optical signal that excites in the optical fiber multiple propagation modes. An output optical signal, which is output from the optical fiber in response to the input optical signal, is recombined with a reference signal derived from the input optical signal, so as to produce a recombined optical signal. The recombined optical signal is detected (108), and the geometrical shape of the optical fiber (106) is estimated based on the detected recombined optical signal.
