Not Accessible

Your library or personal account may give you access

Abstract

Through space-division multiplexing using multicore fiber, simultaneous measurements of DAS and DTS have been achieved based on Φ-OTDR and ROTDR, respectively. Wavelet transform denoising has been employed to improve the temperature uncertainty to 0.5 °C.
