FREE-PROPAGATION OPTICAL TRANSMISSION SYSTEM |
摘要 |
<p>The free space optical transmission system has a digital information signal (S(t)) with luminous transmissions (SRC) and an opto electrical detector (DET) detecting a frequency. The transmitter transmits two luminous waves (W0,W1) at two optical frequencies, one of which is modulated in intensity. The detection frequency is the difference between the two signals transmitted.</p> |
