Abstract
The present technology comprises a single-aperture snapshot multi-spectral imaging device generally consisting of at least a color camera, a customized Octa-Band optical filter, a motorized zoom lens, and an 8-wavelength multi-color LED illumination system. The present technology also comprises a method about designing time sequences and combinations of LED illuminations, along with an unmixing algorithm for 8 MSI images generation. According to the present device and method, it is capable of fast multi-spectral image acquisition speed (<100 milliseconds), fast post-processing speed based on adopting a single aperture system without disparity correction calculation, adjustable FOVs, smaller form factors and lower costs, and high precision of spectral information.
