Title:
透明体の屈折力を決定する方法及びその装置
Document Type and Number:
Japanese Patent JP6454332
Kind Code:
B2
Abstract:
A method for determining a refractive power of a large-surface-area transparent object, such as a windshield, a visual aid, a cockpit glazing, a helmet visor, or the like, includes detecting a first imaging of a first line grating through the transparent object at at least one predetermined point of the object using a camera and determining a line spacing of the first imaging, the rotation of the lines relative to the first line grating or both through use of a computing unit on the basis of the first imaging at the at least one specified point and using the line spacing or rotation of lines to determine the refractive power at the at least one predetermined point of the transparent object.
