WebApr 7, 2024 · According to principles of measurement, these methods can be divided into three categories: (1) time domain measurements (TDMs), (2) frequency domain measurements (FDMs), (3) phase-derived range measurements (PRMs). The TDMs directly detect the flight time of probe signals. WebThe OFDR spatial resolution is determined by the sweep frequency range of the LFM signal rather than the pulse width. Therefore, OFDR can overcome the conflict between spatial resolution and pulse width of the conventional OTDR. However, there are also some problems with OFDR using coherent detection.
