Title:
METHOD AND DEVICE FOR INSPECTING INTERMITTENTLY CONNECTED OPTICAL FIBER TAPE, AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/122375
Kind Code:
A1
Abstract:
[Problem] To inspect an intermittent-connection-type optical fiber tape with high precision despite an increased number of cores in the intermittent-connection-type optical fiber tape. [Solution] This method for inspecting an intermittent-connection-type optical fiber tape comprises: repeatedly capturing an image of an intermittent-connection-type optical fiber tape along the width direction thereof, the intermittent-connection-type optical fiber tape in which connecting parts for connecting adjacent optical fibers are intermittently arranged, while moving the optical fiber tape in the longitudinal direction thereof, and accumulating one-dimensional images in the width direction of the optical fiber tape; and arranging the accumulated plurality of one-dimensional images in a first direction in which pixels constituting part of the primary images are arranged and a second direction orthogonal to the first direction, and creating a two-dimensional image of the optical fiber tape.
