对用于距离绝对测量的波长扫描干涉法的动态测量特性进行了分析。研究结果表明这种方法特别适用于缓变距离的测量或长期监测，而对于较快速变化的距离测量，本文给出了其运动速度的限制，对于波长扫描干涉法的实际应用具有重要的意义 The dynamic measurement of wavelength-swept interferometry for absolute distance measurement was analyzed. The results show that this method is especially suitable for the measurement of long-distance monitoring or long-term monitoring. For the rapid change of distance measurement, this paper gives the limit of its moving speed, which is of great significance for the practical application of wavelength-swept interferometry
