Abstract	Differential Phase information of Φ-OTDR signal is directly extracted based on self-homodyning the Rayleigh backscattered light using a 90° optical hybrid receiver. The proposed method offers a cost-effective solution for quantitative distributed vibration sensing with low computation complexity. © Optica Publishing Group 2021
