英文摘要： The spectrum, polarization and the three-dimensional shape are important physical characteristics for target feature analysis. Multi-modal imaging technology is a powerful tool which can acquire five-dimensional optical information including the above optical information for target sensing and physical analysis. It has great potential in many fields such as biomedicine science, material analysis, forensic appraisal, food and drug safety, biological and cultural relic archaeology. Around the issues of spectral imaging, polarization imaging and surface shape imaging, the research will carry out a novel multi-modal imaging technology based on the principles of dispersion shearing interferometry, micro-polarization modulation and structured illumination. A five-dimensional optical information acquiring model that includes super-resolution spectrum, full-Stokes polarization and three-dimensional shape will be established. The problems of multi-scale nonlinear spectral recovery, full-spatial-resolution Stokes vector recovery and three-dimensional shape recovery with broadband-spectrum structured illumination will be also solved. Besides, the experimental device will be set up and used to verify the principle and analyze the performance. The research will provide a new technology to obtain high dimensional optical information of the scene for precise target analysis.
