Abstract
Disclosed is a method and apparatus for the non-invasive selection of high-quality seeds, based on optical coherence tomography, by which pathogen-infected and pathogen-free seeds can be discriminated in a non-invasive manner. The apparatus is operated by the processes of scanning a seed of diagnostic interest in a non-invasive manner using an optical coherence tomographic unit; processing interference signals of the scanned tomographic images to produce tomographic image data of the seed of diagnostic interest; analyzing the tomographic image data; comparing the analyzed tomographic image data with preset reference tomographic image data; diagnosing the seed of diagnostic interest as a pathogen-infected or pathogen-free seed according to the comparison data; and selecting high-quality seeds according to the diagnosis data. It can screen high-quality seeds with rapidity, convenience, and accuracy at a low cost and is industrially applicable, making a great contribution to agricultural quarantine inspection.
