研究了在非线性脉冲串干涉仪中利用二次谐波干涉条纹的相位作为位置标记检测零光程差的可能性。理论分析表明，二次谐波条纹的相位可以作为检测零OPD的位置标记，与基波的相位相比，它对距离变化的灵敏度系数更高。在非线性脉冲串干涉仪中，测量了基频条纹和二次谐波条纹的相位，比较了它们的过零点在条纹包络峰附近的位置。验证了这两种位置的差异和所提方法的有效性。本文报告的概念和分析为更高精度的绝对距离测量的发展铺平了道路。
The possibility of using the phase of second-harmonic interference fringes as a position marker for detecting the zero optical path difference (OPD) in a nonlinear pulse-train interferometer is investigated. A theoretical analysis showed that the phase of second-harmonic fringes can be used as a position marker for detecting the zero OPD, and compared to the phase of the fundamental wave, it provides a higher coefficient of sensitivity to the change in distance. In a nonlinear pulse-train interferometer, the phases of the fundamental and second-harmonic fringes were measured, and the positions of their zero-crossing points near the fringe envelope peak were compared. A difference between these two positions and the effectiveness of the proposed method were confirmed. The concept and analysis reported herein pave the way for the development of higher-accuracy, absolute distance measurements.
