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.

Abstract: A method for transmitting information includes deriving a transfer function that relates a first image formed over a first area on an end face (38) of a multimode optical fiber (40) and a second image formed over a second area extending over a side (42) of the multimode optical fiber. Optical information is input to the multimode optical fiber through one of the first and second areas. Following transmission of the optical information through the multimode optical fiber, the optical information that is output from the other of the first and second areas is detected and decoded using the transfer function.
