Patent number: 10184893Abstract: Examples relate to providing hyperspectral scanning of a surface. In some examples, motion capture data of unobstructed portions of the surface are captured, and spectral data of the surface are captured through a slit assembly and diffraction grating. The motion capture data are processed to determine a movement of a scanning device. At this stage, the spectral data are translated and rotated based on the movement of the scanning device to generate images that each correspond to a different color channel.Type: GrantFiled: February 27, 2015Date of Patent: January 22, 2019Assignee: Hewlett Packard Enterprise Development LPInventors: Charles M Santori, James William Stasiak, Garry Hinch
