M. Shizuka, N. Hayashi, Y. Mizuno, and K. Nakamura, “Simplified optical correlation-domain reflectometry without reference path,” Appl. Opt., vol. 55, no. 15, pp. 3925-3928 (2016).

We develop a simplified configuration for optical correlation-domain reflectometry (OCDR) without an explicit reference path. Instead, the Fresnel-reflected light generated at the distal open end of the sensing fiber is exploited as a reference light. After the fundamental demonstration, the optimal incident power is found to be approximately 8 dBm. We also show that the loss near the distal end should not be applied, unlike in the case of Brillouin-based OCDR.
