要約
(EN) [Problem] To provide a new technique for performing high-speed and highly reliable quality determinations using optical measurements. [Solution] Super-continuum light including a spectrum that is continuous along at least 1100-1300 nm is emitted from a pulse light source 1 and is then radiated onto a product P, with the pulse of such light being extended by an extending element 2 so that the relationship between the wavelength in a single pulse and an elapsed time is one-to-one. Having penetrated the product P, the light is received by a light receptor 3, and output data is inputted into a determination means 7. A quality determination program 43 of the determination means 7 calculates an absorption spectrum on the basis of the output data, quantifies the same using chemometrics, and compares the quantified value with a reference value, so as to make a quality determination. The product P, if determined to be of poor quality, is then excluded by means of an exclusion mechanism 8.
