Abstract
Sub-meter resolution sensing has been achieved employing linear pre-amplification with Simplex-coded pulses employing DPP-BOTDA. Results demonstrate a spatial resolution of 40 cm over 56km sensing fiber with 1.1°C-22 ??temperature-strain resolution. © 2011 Optical Society of America.File in questo prodotto:
