“In this image, Shun Muroga shows a schematic of near-infrared (NIR) hyperspectral imaging for evaluating molded poly(lactic acid) (PLA) products. Hydrolysis of PLA products, which occurs during melt processing, must be detected rapidly to assure their quality. Partial least squares (PLS) regression was applied to connect NIR spectra and product properties of PLA. NIR imaging combined with the constructed PLS models clearly visualized the differences in the extent of hydrolyzed PLA under varying degrees of crystallization.
