Title:
HYPERSPECTRAL SCANNER
Document Type and Number:
WIPO Patent Application WO/2016/086720
Kind Code:
A1
Abstract:
The present invention relates to the technical field of spectral imaging. Disclosed is a hyperspectral scanner, comprising: a spectral imaging unit for irradiating white light to an object to be scanned, conducting light splitting processing on diffusely reflected light in a current scanning line of the object to be scanned, and receiving light rays in each wave band after the light splitting processing to generate an electrical signal corresponding to the light rays in each wave band; an optoelectronic conversion unit for receiving the electrical signal, conducting analog-to-digital conversion on the electrical signal to obtain a digital signal, transmitting the digital signal to a host computer, and transmitting a drive signal to a mechanical drive unit; and the mechanical drive unit for driving, after receiving the drive signal, the spectral imaging unit to move to a position corresponding to the next scanning line of the object to be scanned. After the scanner of the present invention conducts light splitting processing on the diffusely reflected light, an area array detector receives the light rays in each wave band after the light splitting processing, thus realizing spectral imaging and maintaining the spectral information in each wave band of the object to be scanned.
