    Abstract

    At present, there has been great progress in the field of the point-to-point laser communication technology. In order to search for an effective means of achieving localized laser broadcast communication within a limited range, an effective method of horizontal link laser broadcast communication was presented, and the corresponding verifiable broadcast communication system was designed. In addition, the laser broadcast was systematically studied by one physical model built at the optimal distribution of optical power. First of all, the theoretical model of laser beam expansion and the theoretical model of parallel light curtain were made comparisons and analyzed from the angle of attenuation of optical power, and the optical power loss model of the parallel light curtain was established as a result. Secondly, combined with the theory of optical imaging transformation based on Gaussian beam, the field distribution of far field of parallel light curtain was simulated by one leading optical and illumination design software and the relation between the filed distribution of far field of light curtain and the distance of transmission was revealed. Finally, the superiority and feasibility of the parallel light curtain theory model were verified by field communication experiments in different information channels.
