介绍了一种基于分布反馈半导体激光器和相位调制技术的全光纤自混频干涉仪，用于测量振动目标的位移。DFB激光器的自混合干涉是通过反射激光前方镜面或粗糙目标的光来实现的，相位由外腔内的光纤电光调制器（EOM）调制。采用正弦相位调制解调技术对干扰信号进行分析。实验结果表明，该方法可以重建目标的运动轨迹。将光纤与自混频干涉技术相结合，可以得到结构灵活、精度高的自混频干涉仪。
All-fiber self-mixing interferometer (SMI) based on distributed-feedback (DFB) semiconductor lasers and phase modulating technique is introduced to measure the displacement of a vibrational target. Self-mixing interference occurs in a DFB laser by reflecting the light from a mirror-like or a rough target in front of the laser, and the phase is modulated by a fiber electrooptic modulator (EOM) in the external cavity. The sinusoidal phase modulating and demodulating technique is used to analyze the interference signal. The experimental results indicate that the movement of the target can be reconstructed by this method. Combining the optical fiber with self-mixing interference technique, the flexible structure and high-accuracy self-mixing interferometer can be obtained.
