In order to analyze the loss of the free-space optical receiver caused by the vibration, we set up the coordinate systems on both the receiving lens surface and the receiving fiber surface, respectively. Then, with Gauss optics theory, the coupling efficiency equation is obtained. And the solution is calculated with MATLAB® software. To lower the impact of the vibration, the directional tapered communication fiber receiver is proposed. In the next step, the sample was produced and two experiments were done. The first experiment shows that the coupling efficiency of the receiver is higher than that of the traditional one. The second experiment shows the bit error rate of the new receiver is lower. Both of the experiments show the new receiver could improve the receiving system’s tolerance with the vibration.
