Abstract
Super continuum light having a continuous spectrum over at least 1100 to 1300 nm is emitted from a pulsed light source, is pulse-stretched by a stretching element such that a relationship between a wavelength and an elapsed time in one pulse is one to one, and is radiated to a product. The light transmitted through the product is received by a light receiver, and output data is input to the determination unit. A quality determination program of the determination unit calculates an absorption spectrum from the output data, quantifies the absorption spectrum by chemometrics, and compares the absorption spectrum with a reference value to determine quality. The product determined to be a defective product is excluded by an exclusion mechanism.
