中文摘要： 现有探测仪器没有充分利用客观世界中各种对象本质上独特的时间-空间-光谱稀疏性，导致获取数据太多而感兴趣信息太少、时-空-谱不能兼顾、应用需求广泛而价格昂贵等矛盾的局面。为解决上述难题，本项目将在前期工作基础上重点研究探测对象时-空-谱的稀疏特性、具有压缩感知特点的时-空-谱多维度探测、重构方法，设计具有自主知识产权的可编程分辨率可变的光谱探测模块、多波段红外光学系统、处理与控制软硬件模块，完成系统集成。本项目在“十一五”重点国防基础科研项目和国家自然科学基金重点项目支撑下，验证了压缩感知目标探测新方法的可行性，并研制成功图谱一体化的探测系统原理样机。通过本项目的方法研究、关键模块设计、仪器集成研制，可提供环境科学、生命科学、航空航天科学等前沿科学领域诸多研究对象的时-空-谱综合特性数据和信息，有力推动这些领域的创新和高新技术仪器的发展，具有重大的科学意义和应用价值。

英文摘要： Various objects in the objective world posses unique time-space-spectra sparsity essentially. However, existing detecting instruments did not take full advantage of this feature, leading to such contradictions as huge acquired data vs little interesting information, being incapable of giving attention to all of time, space and spectra, broad application vs expensive instruments. To address these challenges, on pre-working basis, this project will focus on studying time-space-spectra sparsity of objects and researching detection and reconstruction methods with compressive sensing characteristics of object time-space-infrared spectra multi-dimensional features, design such key modules with independent intellectual property rights as programmable resolution-adjustable spectra-optional spectra detector module, multi-band infrared optical system, process and control hardware and software modules and so on, and complete system integration. Under the support of key defense research project and key NSFC project finished during the" Eleventh Five-Year ", this project had verified that the new method of image-spectra integrated target detection was feasible, and developed the prototype of image-spectra integrated detection system. Method study, key modules design and instrument integration in this project can provide time
