Reconstruction hyperspectraleà haute résolutionà partir de mesures de spectrometrie

Abstract : We present in this work reconstruction of a 3D hyperspectral cube from 2D spectrometer data. In fact, the observed cube with two spatial dimensions $(\alpha,\beta)$ and one spectral dimension $\lambda$ is projected on a 2D detector with one spatial dimension and one spectral dimension. However, the instrument is not perfect and introduces a spatial blurring and a spectral blurring, spectrally variable. An algorithm based on the least square approach with convex Huber regularization is proposed to reconstruct the original 3D cube while inverting the blurring introduced by the instrument.
