本文报道在研制熔接光纤耦合器中所建立的动态监测系统。这个系统由于利用了时间延迟技术,不仅能较高精度地数字显示成品光纤耦合器的静态分束比;而且能在器件的制造过程中监测分束比的变化,进而控制工艺,大大提高器件的成品率。

The paper describes our dynamic monitoring system for fused fiber couple manufacture. By using the time delay technique the system not only can indicate accurately by digital display the static power-splitting ratio of fiber coupler, but also can control the change of power-splitting ratio during process of fiber coupler manufacture, consequently increases the finished productivity of fiber coupler.
