提出了一种双通道光纤环形激光器自混合干涉的新方法。基于光纤环形激光器的超越方程，对双通道光反馈输出功率进行了理论推导和仿真。分析了光纤激光器中两个通道的输出变化和模式竞争。用该系统对两个目标的运动进行了测试，并讨论了不同反馈条件下对自混合干扰的影响。实验结果与仿真结果吻合较好，表明平行双通道自混合干涉是一种有效的多位移测量方法。
A new approach for self-mixing interference in fiber ring laser with a parallel dual-channel is presented. The output power of the dual-channel with optical feedback is theoretically deduced and simulated based on the transcendental equation of fiber ring laser. The output variation and modes competition between the two channels in a fiber laser is also analyzed. We demonstrate this system to measure the movement of two targets, and discuss the influence on self-mixing interference under the different feedback conditions. The experimental results show a good agreement with the simulation, and indicate that the self-mixing interference with parallel dual-channel is an efficient approach for multiple displacement measurement.
