APPARATUS AND METHOD FOR DETECTING DEFECT OF OPTICAL FILM

摘要

The present invention relates to an apparatus for detecting a defect of an optical film, and a method therefor. According to one embodiment of the present invention, the apparatus for detecting a defect of an optical film comprises: a receiving unit receiving information on a defect of an optical film roll from at least one inspection device; a defect position determination unit determining a defect position on a two-dimensional plane corresponding to the optical film roll based on the defect information; a searching unit searching an area having at least preset number of defects on the plane based on the position of the defect; and a defect detection unit detecting the periodic defect based on an interval between the defects and the number of the defects contained in the searched area.
