    • A spatial coherent light transmission apparatus according to the present invention, includes: a light transmitter for emitting a data signal as first coherent light; a light receiver for emitting second coherent light having a wavelength little different from that of The first coherent light, mixing and receiving the first and second coherent lights, and performing a coherent detection of the data signal. At least one of the light transmitter and the light receiver has a detection device for detecting at least one of a coherent light transmission state and a coherent light detection state. The apparatus further includes a control device for controlling at least one of the light transmitter and the light receiver based on information of the state detected by the detection device.
    • 根据本发明的空间相干光传输装置包括:光发射器,用于发射数据信号作为第一相干光; 用于发射具有与第一相干光的波长略微不同的波长的第二相干光的光接收器,混合和接收第一和第二相干光,以及执行数据信号的相干检测。 光发射器和光接收器中的至少一个具有用于检测相干光透射状态和相干光检测状态中的至少一个的检测装置。 该装置还包括控制装置,用于根据由检测装置检测到的状态的信息来控制光发射器和光接收器中的至少一个。
