【摘要】 介绍了高光谱成像的需求与应用、光谱成像技术的现状与发展。高光谱成像已在产品分选、精准农业、环境监测、文物保护、刑事侦查、伪装识别等行业得到应用。传统的棱镜光栅色散型、连续可调谐滤光型、傅里叶变换干涉型等光谱成像分光方式成本高、体积大、速度慢,目前其光谱成像仪仍作为主要的研究设备。为促进产业化应用,需要发展体积小、成本低、速度快的光谱成像技术。计算层析、压缩编码、胶体量子点CQDs光谱成像技术仍需理论突破,短时间难以实用。积分视场、离散采样光谱成像技术原理简单、技术成熟,可用于空间分辨率要求不高的场合。复眼滤光式、像素滤光式光谱成像技术通过单片集成像素级滤光片,既能在权衡光谱分辨率与空间分辨率的基础上实现实时性,又能极大地减小体积、降低成本。更多还原

【Abstract】 The hyperspectral industry application,hyperspectral imaging technology and its development are introduced. Hyperspectral imaging data has been used in product sorting,precision agriculture,environmental monitoring,cultural relics preservation,criminal investigation,camouflage identification and other industries. However,the traditional spectroscopic imaging methods,such as prism grating dispersion,continuous tunable filter and Fourier transform interferometry,are still mainly used as scientific research equipment because of their high cost,large volume and slow speed. To promote massive industrial application,spectral imaging technology with compact size,low cost and fast speed is needed. Computational tomography,compressive coding and CQDs(colloidal quantum dots) spectral imaging still need theoretical breakthroughs and are difficult to be applied in a short time. The integral field unit and the discrete sampling spectral imaging technology are simple in principle and mature in technology,which can be used in the occasion of low spatial resolution requirements. The compound-eye filter and the pixel filter spectral imaging technology can achieve real-time performance on the basis of balancing spectral resolution and spatial resolution through a single integrated pixel filter,and can greatly reduce volume and cost.更多还原
