Snapshot dual-band visible hyperspectral imaging spectrometer

Abstract

We describe a proof of concept for a snapshot dual-band visible hyperspectral imaging spectrometer. A commercially available digital camera was integrated into a computed tomographic imaging spectrometer to provide a means for this proof of concept. Two spatially coregistered data cubes covering the blue ͑400 to 500 nm͒ and red ͑600 to 700 nm͒ spectral regions were reconstructed and the results analyzed. We found that the system accurately reconstructs the spectral content of the scene and that the two data cubes are automatically spatially coregistered by virtue of the system design.

Medical hyperspectral imaging: a review

“…Single shot imagers, such as a computer-generated hologram (CGH), are used to disperse light in snapshot HSI systems. 44,76,102 CGH consists of cells of square pixels that are arrayed to form a 2-D grating. CGH enables CTIS to capture both spatial and spectral information in a single frame.…”
