In this case, 1st and 2nd optical filters 22 and 23 are interposed as a filter means between the Bragg diffraction gratings FBG1 to FBG4 and the array waveguide diffraction grating(AWG) 25 of a measurement part 1B and the transmitted lights of the filters 22 and 23 are made incident on the array waveguide diffraction grating 25 by turns.例文帳に追加

前記ブラッグ回折格子ＦＢＧ１〜ＦＢＧ４から測定部１Ｂのアレイ導波路回折格子（ＡＷＧ）２５に至るまでの間に、フィルタ手段として第１、第２の光フィルタ２２，２３を挿入し、各フィルタ２２，２３の透過光を交互にアレイ導波路回折格子２５に入射させる。 - 特許庁

The reflected lights from the respective Bragg diffraction gratings FBG1 to FBG4 are made incident on a diffraction grating type demultiplexer (HOE) 21 which can have its center wavelength separated into small-interval wavelengths and the wavelengths of the reflected lights are measured according to the logarithm of the ratios of photocurrents of couples of photodetecting elements PD provided at output channels of the demultiplexer.例文帳に追加

各ブラッグ回折格子ＦＢＧ１〜ＦＢＧ４からの反射光を、中心波長が微小な間隔の複数波長に分離可能な回折格子型分波器（ＨＯＥ）２１に入射させ、その複数の出力チャンネルにそれぞれ設けられた一対の受光素子ＰＤによる光電流の比の対数に基づいて前記反射光の波長を測定する。 - 特許庁
