Free space optical transmission apparatus |
摘要 |
<p>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. <IMAGE></p> |
