The use of virtual delay lines along with novel self-referencing techniques minimizing resolution and using a single frequency avoids all-optical or electrical-based delay lines approaches at reception. This solution preserves the self-referencing and performance characteristics of the proposed optical sensing topology, and leads to a more compact solution with higher flexibility for the multiple interrogation of remote sensing points. Results are presented for a displacement sensor demonstrating the concept feasibility.4application/pdfeng© (2012) Society of Photo-Optical Instrumentation Engineers (SPIE).Fiber optics sensorsoptical sensingremote sensingsensorspassive remote sensingself-referencingdigital filtervirtual delay line.conference paperElectrónicaIngeniería IndustrialÓpticaTelecomunicaciones10.1117/12.968580open access14Proceedings SPIE, OFS2012 22nd International Conference on Optical Fiber Sensors8421CC/0000019100
