The regularized phase tracking technique used in single closed interferogram phase retrieval
-
摘要: 在利用干涉技术检测温度、压力、形貌等物理量时，往往需要通过各种调制手段将这些物理量的信息加载到干涉条纹图样中，并通过对其进行分析而得到被测信息。当实验条件不利于实验者实施移相、加载波等调制手段时，探测器得到的往往是单幅闭合条纹，此时常用的移相解调技术和频谱分析方法等不再适用。正则化相位跟随(Regularized Phase Tracking，RPT)技术可以对单幅闭合条纹进行相位恢复，是目前针对单幅闭合条纹相位恢复最有效的方法。近年来研究者们从复杂干涉图处理能力、算法稳定性、相位恢复精度等方面对RPT技术进行了改进和发展，使其逐渐走向实用化。本文介绍了RPT技术用于单幅干涉图相位恢复的基本原理，总结了近年来RPT技术的相关改进与发展，例举了采用RPT技术进行相位恢复的应用场合，并适当推测RPT技术的未来发展方向。Abstract: Different kinds of modulation methods are usually adopted when physical quantities, such as temperature, forces and deformation, are measured in interference. Fringe patterns carry measurement information of those quantities and are usually later analyzed for its retrieval. Single closed fringes are generally what is recorded by CCD. When the experimental conditions are not conducive to phase shifting, loading wave and other modulation means, the regularized phase tracking(RPT) technique can retrieve a continuous phase map directly from a single interferogram, making it the most effective method. In recent years, RPT technique has been improved to achieve higher processing power, algorithm robustness and retrieval accuracy for complex fringe patterns, ultimately making it more practical. In this paper, we introduce the basic algorithm principle and how the RPT technique is applied in the retrieval of single interferograms, review the technique's relevant modifications and developments in recent years, cite some examples used for phase retrieval and speculate the direction of its future development.
