Performance of concealed optical wireless communication link based on modulated retro-reflector

Performance of concealed optical wireless communication depends on retro-reflector. The mathematic model of laser beam reflected by CCR was set up in this paper, which was applied in analyzing the effect of atmosphere turbulence on MRR link. Furthermore, the channel compensation of reflecting characteristic of CCR for the received power fluctuation induced by atmosphere turbulence was discussed. The simulation results show that wavelength, angle of incidence, and refractive index of CCR are the key factors influencing the performance of link, and the SNR fluctuation is decreased by reflecting of CCR.
