翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Delay line interferometer ： ウィキペディア英語版 Delay line interferometer A delay line interferometer (DLI) can be a Mach-Zehnder interferometer or Michelson interferometer based on two-beam interference, in which one beam is time-delayed to the other by a desired interval. Delay line interferometers are also known as optical DPSK demodulators. They convert a phase-keyed signal into an amplitude-keyed signal. In this application, an incoming differential phase-shift keying (DPSK) optical signal is first split into two equal-intensity beams in two arms of a Mach Zehnder or Michelson interferometer, in which one beam is delayed by an optical path difference corresponding to ''1-bit'' time delay. After recombination, the two beams interfere with each other constructively or destructively. The resultant interference intensity is the intensity-keyed signal. ==External links== *(Delay line interferometer and Optical DPSK demodulator ) *(All-Fiber Delay line interferometer and Optical DPSK demodulator ) *(Ultra fast Optical DPSK demodulator ) 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「Delay line interferometer」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.
