Hybrid Nonlinear Preamplification for φ-OTDR Distributed Acoustic Sensing
conference paper
A linear-nonlinear preamplification system for φ-OTDR distributed acoustic sensors to counteract signal fading is compared with linear preamplification, showing an improvement in minimum and average intensity of 160% and 73% compared to the maximum.
