Abstract
Currently, Hadamard transform spectral imager with the digital micro-mirror device (DMD) as the optical modulator is one of the most popular research topics in international spectral imaging field. The physical models of DMD-based Hadamard transform spectral imager have been experimentally demonstrated to be feasible. However, the research about how to process the recovered spectral data of this type of spectral imager to reach the standard of engineering applications is quite rare. This paper discusses the spectral data processing method, mainly including the correction for the recovered spectral data and how to decode the interlaced encoding pixels. Eventually, the processing methods proposed is proved to be effective and feasible by experiments.
