beam-pointing angle
解釋
波束指向角-
1550nm is chosen as the work wavelength, cassegrain transmitting - receiving antenna as the optical antenna of the system through the elucidation of how to choose the work wavelength and optical antenna of comm - unication system. the structure and theoretical design parameter of apt sub - system have been presented through the discussion of the optical signal power estimation of apt sub - system, beam divergence angle, pointing error, and error signal extraction. compared with existed optical wireless communication system, the design scheme proves applicable
通過對通信系統工作波長選擇、光學天線選擇等闡述,選擇了1550nm作為系統工作波長、卡塞格倫( cassegrain )收發合一天線作為系統光學天線;通過對apt子系統功率測算、束散角和瞄準誤差、誤差提取信號等的討論,給出了apt子系統結構和理論設計指標,並將其與現有的光無線通信系統進行比較,說明該設計方案是可行的。
