Abstract :
The dual-channel self-mixing vibration measurement system in a linear cavity fiber laser with high sensitivity, flexibility, and potential remote sensing is proposed and studied in this paper. In addition, the output power with optical feedback is theoretically deduced and simulated on the basis of the three-cavity model. Experimental results show that the different movements of each channel can be detected from the dual-channel linear cavity fiber laser self-mixing interference system on the basis of the filter technology and that are in good agreement with the theoretical analysis. In addition, this paper introduces a new way to measure two-dimensional vibration.
