Abstract
(EN)
A hyperspectral imaging system comprising: a first dispersive element to disperse an image moving laterally with respect to an optical axis of the hyperspectral imaging system into N spectral components, a coding mask, in optical communication with the first dispersive element, to encode the N spectral components with a predetermined code, a second dispersive element, in optical communication with the coding mask, to recombine the N spectral components into an encoded image, a detector array, in optical communication with the second dispersive element and having M >/= N detector elements, to detect the encoded image, wherein M and N are positive integers and a processor, operably coupled to the detector array, to form a reconstructed version of the image from the encoded image, the processor configured to estimate the motion blur from the reconstructed version of the image based on the predetermined code.
