In this dissertation, a new class of measuring techniques for non-destructive spatial mapping of fiber physical parameters was developed and experimentally verified. The proposed method is based on selective localization of four -photon mixing (FPM) obtained by power transfer between the counter-colliding pulses and provides at least one order of magnitude increase in spatial resolution over comparable methods. The technique was applied to retrieve geometrical, dispersive, stress, and birefringent properties of distributed fiber devices with meter-scale spatial resolution. The method is capable of resolving fluctuations in fiber transversal geometry comparable to a silica molecular diameter
