Abstract
Provided is a high-speed and high-accuracy tablet spectroscopic measurement technology that enables total inspection. A pulsed light irradiation system irradiates a tablet being linearly moved by a movement mechanism with pulsed light in which an elapsed time in each pulse and a wavelength correspond to each other on a one-to-one basis, the output from a light receiver that has received transmission light from the tablet is input to a calculation means via an AD converter and an FPGA as an integration means, and a spectral transmission spectrum is calculated. In a case where the variation in spectral characteristic is measured, grouping is performed for multiple times of pulsed light irradiation performed on different locations, integration is separately performed, spectral transmission spectra are calculated and then compared.
