Fig. 2: Comparison between conventional HSI techniques and the reported SpectraTrack.
From: SpectraTrack: megapixel, hundred-fps, and thousand-channel hyperspectral imaging
A Principles of the conventional HSI frameworks including spatial-scanning-based, spectral-scanning-based, and compressed-acquisition-based ones. B Principle of the reported SpectraTrack technique. We first capture the multiplexed HSI measurement of dynamic scenes via spatial scanning. Each row of the measurement corresponds to a slice of the target’s hyperspectral information cube at a moment. The measurement was then utilized to reconstruct the spectra at the corresponding position of each moment’s hyperspectral scene in the scanning process. Motion information captured by the auxiliary array camera guides the reconstruction.
