The large aerial display uses a large acrylic panel. However, the acrylic plate is distorted by their own weight, causing distortion in the aerial image formed. In this study, the distortion of large acrylic plate installed in a large aerial display was measured to approximate a cylindrical shape. By measuring the shape of both sides of the acrylic plate and approximating it to a cylinder, it is clear that the acrylic plate has a cylindrical shape with a radius of curvature of about 618 cm.
