This paper reports the design and construction of a low-cost, multispectral imaging system using a single, large format CCD and an array of 18 individual lenses coupled to individual spectral filters. The system allows the simultaneous acquisition of 18 subimages, each with potentially different optical information. The subimages are combined to create a composite image, highlighting the desired spectral information. Because all the subimages are acquired simultaneously, the composite image shows no motion artifact. Although the present configuration uses 17 narrow bandpass optical filters to obtain multispectral information from a scene, the system is designed to be a general purpose, multiaperture platform, easily reconfigured for other multiaperture imaging modes.
本文报道了一种低成本多光谱成像系统的设计与构建，该系统使用单个大幅面电荷耦合器件（CCD）以及与单个光谱滤光片耦合的18个独立透镜阵列。该系统能够同时采集18幅子图像，每幅子图像都可能具有不同的光学信息。这些子图像被组合起来以创建一幅合成图像，突出所需的光谱信息。由于所有子图像是同时采集的，合成图像中没有运动伪影。尽管当前配置使用17个窄带通光学滤光片从场景中获取多光谱信息，但该系统被设计为一个通用的多孔径平台，可轻松重新配置以用于其他多孔径成像模式。
