WINDING DEVICE, WINDING METHOD, INSPECTION DEVICE AND STRUCTURE MANUFACTURING METHOD

摘要

Provided is a winding device provided with: a dividing section (303) that divides emitted light from a light source unit into measurement light that is shone onto a side surface section (204e) of a first sheet and second sheet and reference light that is shone onto a reference surface (311); an interference detection section (314) that detects interference light wherein the reference light reflected by the reference surface interferes with the measurement light reflected by the side surface section; a position detection section (314) that on the basis of the interference light detected by the detection section, detects the positions of the first sheet and second sheet; and an assessment unit (100c) that on the basis of the positions detected by the position detection section, performs a pass/fail assessment of a winding body.
