用于强度解调型非本征法布里-珀罗腔光纤传感器的光电转换卡

Photoelectric Conversion Card Applied in Intensity-Modulated Extrinsic Fabry-Perot Cavity Optical Fiber Sensor

利用双光路加参考臂的方法设计了运用于强度解调型非本征法布里-珀罗腔光纤传感器的新型光电转换卡,以有效地抑制或消除光源和光路中其他有源及无源器件的不稳定性对传感器精度和稳定性的负面影响。在26℃28℃的环境温度条件下,设计的光电转换卡短期不稳定性不大于0.0702%,测量精度好于0.1%。

Method of double optical paths with a reference arm is applied to design a novel photoelectric conversion card to restrain or eliminate the adverse influences induced by the instabilities of light source, other active and passive apparatuses. Under the temperature of 26 ℃～28 ℃, the short-term instability of less than 0.0702% and measurement precision of better than 0.1% are obtained.
