使用光束相干偏振矩阵方法,推导出非均匀偏振光束通过环状光阑后偏振度和光强分布的表达式,研究了非均匀偏振光束通过环状光阑后偏振度和光强的变化。结果表明,在横平面上通常偏振度为非均匀分布,但在中心区域近似为均匀分布,均匀分布范围与非均匀偏振光束参数、光阑遮拦比和传输距离有关。初始为均匀分布的光强通过光阑后变为具有中心主极大和小衍射旁瓣的非均匀分布。

Joint Multimodal Aspect-based Sentiment Analysis(JMASA)is a significant task in the research of multimodal fine-grained sentiment analysis,which combines two subtasks:Multimodal Aspect Term Extraction(MATE)and Multimodal Aspect-oriented Sentiment Classification(MASC).Currently,most existing models for JMASA only perform text and image feature encoding from a basic level,but often neglect the in-depth analysis of unimodal intrinsic features,which may lead to the low accuracy of aspect term extraction and the poor ability of sentiment prediction due to the insufficient learning of intra-modal *** this problem,we propose a Text-Image Feature Fine-grained Learning(TIFFL)model for ***,we construct an enhanced adjacency matrix of word dependencies and adopt graph convolutional network to learn the syntactic structure features for text,which addresses the context interference problem of identifying different aspect ***,the adjective-noun pairs extracted from image are introduced to enable the semantic representation of visual features more intuitive,which addresses the ambiguous semantic extraction problem during image feature ***,the model performance of aspect term extraction and sentiment polarity prediction can be further optimized and *** on two Twitter benchmark datasets demonstrate that TIFFL achieves competitive results for JMASA,MATE and MASC,thus validating the effectiveness of our proposed methods.

本文采用重叠关联迭代引擎算法,系统地模拟研究了扫描相干衍射成像中中心挡板导致的低频信号丢失对重建图像质量的影响.结果表明,扫描相干衍射成像对中心挡板的承受能力远大于平面波单次相干衍射成像,且选择小尺寸入射探针和较高重叠度(70%)可进一步降低中心丢失信号对扫描相干衍射成像的负面影响.另外,光斑扫描位置误差在重叠度较高时将超过中心挡板成为扫描相干衍射成像最主要的负面影响因素.本文研究结果对扫描相干衍射成像实验中如何应用中心挡光板具有重要的指导意义,将有助于进一步提高扫描相干衍射成像的分辨率.
