    它利用接收到的戰場主要目標運動時發出的噪聲作為研究對象，自己不發出信號，從而具有較強的隱蔽性。
  7. So, mfld provides a new way to obtain optical information for optical chemo - and biosensors. compared with conventional detection methods, in which the detector was placed at the distal end of the fiber, mfld has advantages in much higher singnal - to : noise ( s / n ) ratio and sensitivity, since the analyte signal is measured against a much lower background by placing the detector at the fiber - optic profile instead of the distal end

    模式濾光檢測和傳統的檢測方式相比，檢測器的位置由光纖末端改放在光纖側面，獲取光纖側面產生的模式濾光信號，由於光纖側面的背景光遠較光纖末端的出射光背景小，因而較之檢測光纖末端的出射光有高得多的信噪比和靈敏度。
