We have proved out polarization modulation can reduce or even eliminate the that it is doable to utilize the polarized light in FSO (Free Space influence of atmospheric channel, and improve the system Optical Communication) system. The scheme of optical reliability, and at the same time it can also improve the polarization FSO-OFDM is advanced aimed at the format of the system confidentiality. OFDM signals, and the principles of the transceivers are expatiated. At last, this scheme is confirmed by Monte Carlo approach, which shows that performance of the light polarization II. THE POLARIZED LIGHT PROPERTIES FSO-OFDM system is very stable. As we all know that only transverse
