翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Differential group delay ： ウィキペディア英語版 Differential group delay In optics, differential group delay is the difference in propagation time between the two eigenmodes ''X'' and ''Y'' polarizations. Consider two eigenmodes that are the 0° and 90° linear polarization states. If the state of polarization of the input signal is the linear state at 45° between the two eigenmodes, the input signal is divided equally into the two eigenmodes. The power of the transmitted signal ''E''''T'',total is the combination of the transmitted signals of both ''x'' and ''y'' modes. : $E\_T\; =\; (E\_\; \backslash cdot\; t\_x)^2\; +\; (E\_\; \backslash cdot\; t\_y)^2\; \backslash ,$ The differential group delay ''D''''t'' is defined as the difference in propagation time between the eigenmodes: ''D''''t'' = |''t''''t'',''x'' − ''t''''t'',''y''|. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Differential group delay」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
