Abstract

Very recently, for higher-speed distributed measurements of strain and temperature, we have developed a new configuration of Brillouin optical correlation-domain reflectometry (BOCDR)-slope-assisted (SA-) BOCDR-, which utilizes the spectral power of Brillouin gain spectrum. Its basic operation has already been clarified and further studies are being carried out extensively. However, a detailed study on the measurement sensitivity has not been performed yet. Hence, in this work, we experimentally investigate how the spatial resolution and the incident power affect the measurement sensitivity of SA-BOCDR.
