| 摘要 |
The present invention is directed to a coherent gated receiver. The recei ver includes a decoder operable to receive an optical signal and generate a decoded optical signal, the decoder comprises a demultiplexer operable to sp atially distribute the optical signal, a phase mask operable to decode the s patially distributed optical signal, and a multiplexer operable to combine t he decoded spatially distributed optical signal. The receiver also includes a laser source operable to provide a pulse signal, a combiner coupled to the laser source and the decoder operable to combine the decoded optical signal and the pulse signal, and a detector operable to detect an output from the combiner.
