Quantum Noise Limited Temperature-Change Estimation for Phase-OTDR Employing Coherent Detection
Huwei Wang, Roman Ermakov, Francesco Da Ros +1
The quantum limit is a fundamental lower bound on the uncertainty when estimating a parameter in a system dominated by the minimum amount of noise (quantum noise). For the first ti…

Low-Complexity Event Detection and Identification in Coherent Correlation OTDR Measurements
Jasper Müller, Ognjen Jovanovic, Florian Azendorf +7
Pairing coherent correlation OTDR with low-complexity analysis methods, we investigate the detection of fast temperature changes and vibrations in optical fibers. A localization ac…
