Coded aperture optimization for compressive X-ray tomosynthesis

Radiation dose is a concern in X-ray tomographic imaging; coded aperture compressive X-ray tomosynthesis is an approach used to reduce radiation. It places a coded aperture in front of an X-ray source in order to obtain 2D patterned projections of a three-dimensional object ont...

DMD-based implementation of patterned optical filter arrays for compressive spectral imaging

Compressive spectral imaging (CSI) captures multispectral imagery using fewer measurements than those required by traditional Shannon?Nyquist theory-based sensing procedures. CSI systems acquire coded and dispersed random projections of the scene rather than direct measurements o...

Snapshot colored compressive spectral imager

Traditional spectral imaging approaches require sensing all the voxels of a scene. Colored mosaic FPA detector-based architectures can acquire sets of the scene?s spectral components, but the number of spectral planes depends directly on the number of available filters used on th...

An introduction to compressive coded aperture spectral imaging

Imaging spectroscopy involves the sensing of a large amount of spatial information across a multitude of wavelengths. Conventional approaches to hyperspectral sensing scan adjacent zones of the underlying spectral scene and merge the results to construct a spectral data cube....

Fast lapped block reconstructions in compressive spectral imaging

The coded aperture snapshot spectral imager (CASSI) senses the spatial and spectral information of a scene using a set of K random projections of the scene onto focal plane array measurements. The reconstruction of the underlying three-dimensional (3D) scene is then obtained by l...

Code aperture optimization for spectrally agile compressive imaging

Coded aperture snapshot spectral imaging (CASSI) provides a mechanism for capturing a 3D spectral cube with a single shot 2D measurement. In many applications selective spectral imaging is sought since relevant information often lies within a subset of spectral bands. Capturing...
