HS image acquisition process. (a) The imager scans the desired scene during its motion. The LCC is aligned with the direction of motion to perform different spectral encoding for each strip of the imaged scene. (b) The imaged scene gradually travels along the LCC over time, allowing recording differently spectrally multiplexed measurements of each strip of the scene. (c) The set of acquired images (left) is registered and aligned (right) according to the spatial context of the imaged scene, which is marked by a dashed red outline of a cube. (d) Through spectral demultiplexing, a HS data-cube of the imaged scene (right) is reconstructed from the acquired spectrally multiplexed HS data-cube (left) of the scene.
