摘要
干涉图像区域分割属于重要的干涉图像预处理步骤,目的是从干涉图像中提取出有效数据区域。干涉图像区域分割广泛存在于各种数字波面干涉仪的实验测试和数据处理中,对于精确波前复原以及相位解包裹可靠实施具有重要影响。介绍了3类常见干涉图像的区域分割技术,包括单帧干涉图、同步移相干涉图和横向剪切干涉图,并系统总结了相关研究进展、展望了该领域研究趋势。
The region segmentation is an important pre-processing step in optical interferogram processing,in which the effective region is extracted from interferogram.The region segmentation of interferogram widely exists in the experimental testing and data processing of various digital wavefront interferometers.It has important influence on accurate wavefront retrieval and reliable implementation of phase unwrapping.The paper introduces the region segmentation technology of three kinds of popular interferogram,including single-frame interferogram,simultaneous phase-shifting interferogram and lateral shearing interferogram.The related research progress is systematically summarized,and the research trend in this field is also prospected.
