We propose a novel technique for chaotic correlation optical time domain reflectometer with millimeter and range-independent spatial resolution. Utilizing chaotic waveforms generated from a laser diode with an optical fiber ring feedback a proof-of-concept experiment is demonstrated with 6-cm spatial resolution in the 0 similar to 140 m range, which is limited by the bandwidth of the real-time oscilloscope used.
