摘要
An optical coherence tomography (OCT) system (63) is used to inspect bonding points (66A, 66B, 66C) sandwiched between two materials (layers 62, 64 of e.g. displays). The OCT differentiates between a bonding point, e.g. a weld, and air gaps between the two materials. The bonding points are identified as breaks in the air gap between the materials. By extracting various physical characteristics of the bonding points and the gap between the two materials, the present system determines whether the bonding is faulty.
