    摘要: A phase difference measurement device comprises at least two optical waveguides arranged in parallel in a first plane. Each optical waveguide comprises a proximal portion and a distal portion. The proximal portion of at least one of the optical waveguides comprises a phase-shifting device configured to induce a phase shift of a light wave being transmitted in the phase difference measurement device. The device further comprises at least one phase interrogator device arranged in the first plane between two neighboring optical waveguides of the optical waveguides. The phase interrogator device is configured to couple light from the two neighboring optical waveguides to interfere in the phase interrogator to generate an interference light wave. At least one photodetector is arranged for detecting the interference light wave. The photodetector is arranged in a second plane other than the first plane.
