Compressive Sampling for Spectral Imaging

Not Accessible

Your library or personal account may give you access

Abstract

Active spectral imaging in the mid-infrared can reveal absorption ‘fingerprints’ of different chemicals within a scene. The practicality of spectral imaging with active illumination is limited by the large number of images required (as the illumination wavelength or an interferometer mirror is scanned). Single pixel imaging uses the intensity reading from a single pixel detector while illuminating the scene with a series of speckle patterns, and reconstructs the image using a projection algorithm [1]. We have followed this approach, using an algorithm to reconstruct spectral information, rather than spatial.
