A DATA-EFFICIENT AND SELF ADAPTING IMAGING SPECTROMETRY METHOD AND AN APPARATUS THEREOF

摘要

A method (Fig.2) for spectral imaging includes capturing high spectral resolution data of at least a portion of an image using a plurality of channels, determining a first set of channels from the plurality of channels (element 31) which can reconstruct spectra of the portion of the image to within a first error tolerance from the captured high spectral resolution data, and capturing estimated spectral resolution data of the image using the first set of channels (element 35).
