| Abstract: | Based on the analysis of sodium spectrum characteristic in upper atmosphere and laser spectrum characteristic, this paper proposes a suitable frequency matching relationship between echoed signal of sodium laser guide star and sodium atomic cell fluorescence in principle. The preparation of laser guide star can be achieved by intelligentized laser frequency locking. And the imaging of sodium laser guide star can be obtained by imaging telescope and single-lens reflex camera. Meanwhile, some important parameters of preparation and imaging such as laser intensity, photon echoes can be got by lidar. |
