一个完全干涉技术获得超多光谱成分的三维（3D）图像已被测试的多色对象，包括空间不相干的，不同形状的平面光源。每个平面源具有不同的连续光谱，位于不同的3D位置。该方法基于五维（5D）干涉图的测量。通过应用合成孔径技术和光谱分解的5D干涉图，人们获得了一组不同光谱分量的复全息图。从这些全息图中，已经检索到多个光谱分量的3D图像。还示出了每个平面光源的分解的连续光谱，以证明在由白色光照射下识别物体的特定部分的材料的潜在适用性。
A fully interferometric technique for obtaining hypermultispectral components of three-dimensional (3D) images has been tested for a polychromatic object that consists of spatially incoherent, planar light sources of different shapes. Each planar source has different continuous spectra, located at different 3D positions. The method is based on measurement of a five-dimensional (5D) interferogram. By applying synthetic aperture technique and spectral decomposition to that 5D interferogram, one obtains a set of complex holograms of different spectral components. From these holograms, 3D images of multiple spectral components have been retrieved. A decomposed continuous spectrum of each planar light source is also shown to demonstrate the potential applicability to identify materials of a particular part of an object under illumination by white light.
