H. Lee, Y. Mizuno, and K. Nakamura, “Measurement sensitivity dependencies on incident power and spatial resolution in slope-assisted Brillouin optical correlation-domain reflectometry,” Sens. Actuat. A: Phys., vol. 268, pp. 68-71 (2017).

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.
