Real-time Microwave Photonic technique for Low-Coherence Interferometry applications

SCM Adaptation to Improve Scanning Rate in RF Interferometry Applications

“…Combination of MWP and LCI (MWP-LCI) has become an attractive solution as can be seen in some recent publications [9][10][11][12][13]. Different proposals can be found where the slicing of an incoherent source and its analysis through a dispersive element has been demonstrated to retrieve the visibility of low-coherence interferograms by measuring the electrical transfer function in the RF domain [9][10][11].…”

“…Different proposals can be found where the slicing of an incoherent source and its analysis through a dispersive element has been demonstrated to retrieve the visibility of low-coherence interferograms by measuring the electrical transfer function in the RF domain [9][10][11]. Nevertheless, the scanning rate of these proposals is restricted to the sweep speed of commercial equipments [13]. In order to achieve high scanning rates, time domain techniques including high speed oscilloscopes have been proposed [12].…”

“…In order to achieve high scanning rates, time domain techniques including high speed oscilloscopes have been proposed [12]. Comparing optical and RF domain, the inherent stability of RF domain techniques is a relevant advantage to improve LCI key parameters such as resolution and sensitivity [13].…”
