phase-sensitive detectorとは 意味・読み方・使い方

A phase difference between the driving voltage and an electric current is found in a PSD (Position Sensitive Detector) circuit 69.例文帳に追加

ＰＳＤ回路６９で、駆動電圧と電流の位相差を求める。 - 特許庁

Since the change in light quantity due to wavelength sweep in laser beams of two systems is canceled, a step at the time of wavelength switching is relaxed in an output of the optical detector 10, and as a result, the occurrence of high-frequency noise in phase-sensitive detection is reduced.例文帳に追加

２系統のレーザ光における波長掃引に伴う光量変化は相殺されるため、光検出器１０の出力では波長切替え時の段差が緩和され、その結果、位相敏感検波における高周波ノイズの発生も軽減される。 - 特許庁
