摘要：

In interferometers which employ internal modulation schemes, radiation from the detector port of the instrument can contribute to the detected interferometrically modulated signal. This can cause the spectrum measured in a power transmission or reflection experiment to be significantly different from the corresponding real spectrum of the specimen. A measurement procedure that allows the effect of this detector port radiation to be removed is described and demonstrated.
