Fundamentals of Optical Fiber Sensing Schemes Based on Coherent Optical Time Domain Reflectometry: Signal Under Dynamic Temperature Conditions
Roman Ermakov, Huwei Wang, Florian Azendorf +4
We present a theoretical, algorithmic, and experimental study of temperature sensing using -OTDR with coherent detection. A physics-based model is developed to relate the measur…

Estimating Magnetic Filling Factors From Simultaneous Spectroscopy and Photometry: Disentangling Spots, Plage, and Network
T. W. Milbourne, D. F. Phillips, N. Langellier +21
State of the art radial velocity (RV) exoplanet searches are limited by the effects of stellar magnetic activity. Magnetically active spots, plage, and network regions each have di…
