==Original Abstract Submitted==

A coherent detection method and device, and an optical transmission system are disclosed. The method may include: acquiring an optical transmission signal and a local oscillator signal, where a frequency value of the local oscillator signal differs from a frequency value of the optical transmission signal by a preset offset frequency value, the preset offset frequency value being smaller than a symbol rate value of the optical transmission signal; obtaining a coupled signal according to the optical transmission signal and the local oscillator signal; converting the coupled signal into an analog signal; sampling the analog signal according to a preset sampling frequency value and converting the analog signal into a plurality digital signals; and processing two digital signals among the plurality of digital signals so that a phase difference between the two digital signals to is 90 degrees.
