Abstract

In this paper, a technique to simulate the propagation of laser beam in the inter-satellite communications in a lab room is proposed. The whole system consists of an optical Fourier transformer to generate the far-field of beam following multiple optical magnifiers to amplify the field, and a pin-hole of equivalent receiver aperture to detect the signal of beam. By suitable designs, the power of the received beam signal can be equivalently equal to that in the inter-satellite communication. In addition, a white-light source is introduced into the system to provide an actual noise environment for the further study of bit error due to the signal-to-noise ratio. The total length of the proposed system measures no more than tens of meters, and can be easily assembled in a room space. Correspondingly, the atmospheric effect is negligible. In the paper, the detailed designs of simulative systems are given and a primary experiment is demonstrated, too.
