We develop a simplified approach for localized temperature measurement at the fiber tip, utilizing the standard configuration of Brillouin optical correlation-domain reflectometry (BOCDR) with sinusoidal modulation of optical frequency. This method eliminates the need for specialized modifications to the sensing fiber, thereby enhancing cost-efficiency. Compared to the noise-modulated low-coherence BOCDR, our approach allows for a more precise evaluation of theoretical spatial resolution. We successfully attain a theoretical spatial resolution of 5.7 cm with this method.
