Claim 0:
1. A decoherence processing method, applied to a coherent light receiving device, the coherent light receiving device comprising a plurality of photoelectric conversion units, the method comprising:
comparing, for each of at least two of the plurality of photoelectric conversion units, a phase of an electrical signal converted by the photoelectric conversion unit with a phase of a reference signal to obtain a corresponding phase difference;
performing, for each of at least two of the plurality of photoelectric conversion units, based on the obtained phase difference, phase compensation on the electrical signal converted by the photoelectric conversion unit, to obtain at least two compensated electrical signals of photoelectric conversion units; and
superimposing the at least two compensated electrical signals of photoelectric conversion units and outputting an electrical signal obtained by the superposition.
