Abstract

For rectilinear mobile/free-space optical (RM-FSO) links, laser beam divergence and deflection angles are key factors to get highly accurate receiving power. The effective receiving area of the receiving-lens (R-lens) is presented and used to investigate receiving power under different circumstances. By comparing the optical spot size on the receiving plane with the R-lens diameter, the effects of laser beam divergence and deflection angles on receiving power are analyzed. The results show that the theoretical simulation is basically consistent with the experimental data, and the errors are given. Thus, given different moving situations of RM-FSO links, the solution can be used to analyze the receiving power more effectively by considering the effect of laser beam divergence and deflection angles.
