摘要:

利用恒温控制平台,通过测量干涉光电流和干涉仪两臂光电流的方法,实现了对全光纤干涉仪两臂初相位差的测量。由于光纤对温度的敏感性,研究零差光纤干涉仪相位测量的温度特性是必要的。由实验数据分析可知,零差光纤干涉仪两臂相位差的变化量和温度变化量成线性关系,这与理论分析结果是一致的。在以往的文献中,还没有关于此方面的定量研究。

Abstract:

We calculate the initial phase difference of the homodyne fiber interferometer by measuring the interference photocurrent and the photocurrents from the two fiber arms on a temperature control plat. The fiber is very sensitive to the variation of temperature, so it is necessary to study the temperature characteristics in the phase measurement of homodyne fiber interferometer. By the experimental study of this paper, we can know that the variation of the phase difference of the two fiber arms is proportional to the variation of the temperature. This conclusion agrees well with the theory analysis. To my knowledge, the quantitative research on this aspect is seldom mentioned before.
