Abstract
(EN)
In the present invention, a support device is used to support a central part of a circular optical film, a measurement device disposed in a position shifted radially outward from the central part of the optical film is used to measure the distances between the measurement device itself and each location on a circle having the central part as the origin thereof, and curling information indicating the curling of the optical film is derived on the basis of the distances measured by the measurement device.
(FR)
Dans la présente invention, un dispositif de maintien est utilisé pour maintenir une partie centrale d'un film optique circulaire, un dispositif de mesure disposé dans une position décalée radialement vers l'extérieur depuis la partie centrale du film optique est utilisé pour mesurer les distances entre le dispositif de mesure lui-même et chaque emplacement sur un cercle ayant la partie centrale pour origine, et des informations de gondolage indiquant le gondolage du film optique sont déduites en fonction des distances mesurées par le dispositif de mesure.
(JA)
円形状の光学フィルムの中心部を支持装置で支持し、該光学フィルムの中心部から径方向外側にずれた位置に配置された測定装置によって、該測定装置自身と前記中心部を起点とする円周上の各所との間の距離を測定し、測定装置で測定した距離に基づいて光学フィルムのカールを示すカール情報を導出する。
