  • Method and system for estimating convergence of changes in dimensions of molded article over time
    Patent number: 11879722
    Abstract: An objective of the present invention is to provide a method, or the like, for estimating the convergence of dimensional changes in a molded article over time, by utilizing the polarization intensity of terahertz waves. The present invention provides a method for estimating the convergence of changes in the dimensions of a molded article over time, the method comprising: irradiating a molded article with terahertz waves at multiple positions thereon, wherein the molded article is irradiated with the terahertz waves at each position thereon in multiple orientations about the optical axis; measuring polarization intensities of the terahertz waves transmitted through or reflected from the molded article; and determining whether the polarization intensities at the multiple positions are in a given relationship with each other.
