Denoising of Brillouin Gain Spectrum Images for Improved Dynamic Measurements of BOTDR
Published 2023-01-01Get full textBrillouin optical time-domain reflectometry (BOTDR) is widely used for strain and temperature measurements in various fields. However, the accuracy and reliability of the measurements are often limited by the noise in the sensor signals. Dynamic measurement of BOTDR requires small averaging number a...

Dynamic modulus and damping ratio of organic-matter-disseminated sand under cyclic triaxial condition
Published 2025-06-01Get full textIn Hainan Province, China, the unique geographical location presents significant challenges to the safety of coastal infrastructure due to complex dynamic loads such as waves, sea breeze and earthquake. A type of organic matter-rich and poorly graded organic-matter-disseminated sand (OMDS) is common...
