Abstract :
We propose and demonstrate a novel method of distribution sensing of Doppler-shift frequency, by applying synthesis of delta-function-like optical coherence function (SOCF) to laser Doppler velocimetry. SOCF is a technique to resolve longitudinal position information along one arm of a laser-interferometric system. Distribution of the Doppler frequency is successfully measured in experiments.
