Abstract

In this paper, a packaged erbium-doped fiber amplifier (EDFA) is integrated into a fiber ring to form an erbium-doped fiber ring (EDFR) laser which is applied to measure the particle size based on the self-mixing Doppler effect. A detailed analysis is addressed to introduce the measurement principle, and the obtained results demonstrate that the diameter of the Brownian particles in water can be measured by detect the variations of the intensity and frequency of the fiber laser. This technique can be used in biology, process engineering and chemistry.
