Quality Control of Sugar Beet Seeds With THz Time-Domain Spectroscopy

Sugar beet seeds have a comparably high rate of defective seeds of about 35%-40% which are discarded before dissemination in the field. The separation of proper and defective seeds is a complex and labor-intensive process. We show how THz time-domain spectroscopy can be used for the examination of the seeds including an algorithm for automated classification of the seeds.
