Abstract (in Japanese) (See Japanese page) 
(in English) Optical fiber reflectometry has been widely studied as a method for diagnosing the soundness of fiber networks. Of numerous reflectometry configurations reported so far, optical correlated-domain reflectometry (OCDR) has attracted considerable attention in a wide range of fields including LiDAR applications because of its high spatial resolution and the capability of measuring arbitrary points at high speed (referred to as random accessibility). To date, the experimental setup of OCDR has been simplified to reduce its size and cost by removing an acousto-optic modulator (AOM) used for heterodyne detection and by removing the reference path. If multiple erbium-doped fiber amplifiers (EDFAs) inserted in the optical signal path can be additionally removed, the system will be super-simplified by the inherent use of only an optical source and a photo detector; however, such a trial has not been reported yet. In this work, we implement a super-simplified OCDR system with no use of the EDFAs, AOM, and reference path used in the conventional systems. We experimentally show that this system can still perform distributed reflectivity sensing with a moderate signal-to-noise ratio, which will boost the portability and cost efficiency of the OCDR technology.
