摘　　要：利用光纤参量振荡器(FOPO)进行全光时钟提取需要克服FOPO环长不稳定的问题。通过对LabVIEW、单片机、步进电机和光纤延迟线等模块的整合,研制出适宜FOPO腔长稳定的自动控制方案,利用腔长自动补偿获得稳定的时钟信号。Overcoming the instability of the fiber length of FOPO is required in order to extract clock signals from FOPO. The long-term instability of FOPO is primary due to the mismatch of the length of FOPO resulting from the change of temperature, which degrades the quality of clock signals. This paper develops an optical de- lay line （ODL） suitable for controlling the stability of the length of FOPO through the integration of modules including LabVIEW, SCM, and stepping motor. Based on the automatic compensation of the length of FOPO, stable optical clock signals can be obtained
