Abstract

A novel fiber optic sensor is proposed to achieve the measurement of single microparticle velocity in a two-dimensional space by translating the cores of a multicore fiber in their respective directions into independent spatial filters. The measurement of particle velocity with the accuracy of better than 2% and direction angles in a range from 0° to 120° is achieved. Compared with the previous method by means of manual-assembled fiber array, the measurement accuracy can be increased by using only one multicore fiber probe with the features of compact size and low cost. The technique has potential particle velocity measurement applications in environmental monitoring, biological study and combustion research.
