| Abstract: | To enable high-speed distributed strain and temperature measurements, we have recently developed a new configuration of Brillouin optical correlation-domain reflectometry (BOCDR), called slope-assisted (SA-) BOCDR, which exploits the slope power of the Brillouin gain spectrum. Although its fundamental operations have been already clarified, a detailed study on the measurement sensitivity has not been performed yet. Here, we investigate the influences of the incident power and the spatial resolution on the measurement sensitivity of SA-BOCDR. The sensitivity is found to be improved with increasing incident power and/or lowering spatial resolution, which is verified through distributed temperature measurements. [ABSTRACT FROM AUTHOR] |
