TY - CONF A1 - Shaheen, Sabahat A1 - Konstantin, Hicke T1 - Measurement of Geometric Phase using a φ-OTDR setup N2 - Geometric phase showing sensitivity to changes in polarisation state (SOP) and intensity of backscattered light is measured using a novel φ-OTDR setup based on coherent heterodyne detection. Principle is demonstrated using a polarisation scrambler inline a fiber-under-test.
