Abstract: A polishing system performs chemical-mechanical polishing of an object to be polished using an abrasive slurry. The polishing system includes a polishing amount calculator that measures an amount of free metal ions of a metallic element derived from the object to be polished in a processed slurry and calculates a polishing amount of the object to be polished from the amount of the free metal ions. The object to be polished is a glass containing the metallic element of Group 1 or Group 2 of a periodic table.

Abstract: Provided is a quality inspection method in which an inner state of a three-dimensional laminated molding can be quickly and easily inspected without destroying the three-dimensional laminated molding. To this end, the quality inspection method uses an X-ray Talbot imaging system 1 which creates a reconstructed image of an inspection object on the basis of a moire image obtained by using an X-ray detector to read X-rays which, after being radiated from an X-ray source 11a, have passed through: a plurality of grids in which a plurality of slits S are arranged in a direction perpendicular to the radiation axis direction of the X-ray; and an inspection object H placed on a subject table 13. The inspection object H is a three-dimensional laminated molding formed into a three-dimensional shape by laminating multiple layers of constituent materials. The reconstructed image is created while the inspection object H is placed on the subject table 13 in such a way that at least the lamination direction of layers constituting the inspection object H and the arrangement direction of the plurality of slits S in the plurality of grids are parallel. The inner state of the inspection object H is inspected on the basis of the reconstructed image.
