• What is OCT?

  Optical coherence tomography (OCT) is an advanced optical inspection technology that uses near-infrared light to image internal structures without contact or damage. Originally developed for retinal imaging in medicine, it is now used for quality inspection in semiconductor, display, battery, and other industrial applications.
  
  OCT uses light interference to generate precise micrometer-scale 3D tomographic images. This enables accurate analysis of internal defects, interlayer thickness, bonding conditions, and other features that cannot be identified visually or through conventional inspection methods.

Core Technology Advantages

Non-Destructive Inspection

Inspects internal structures without cutting or damaging the sample. Unlike destructive methods, it avoids product loss, supports 100% inspection, and can be integrated directly into production lines.

3D Internal Vision

Visualizes hidden subsurface structures in three dimensions. Individual layers in multilayer structures can be examined separately, with precise depth-direction cross-sectional images provided in real time.

AI-Powered Analysis

Deep-learning AI automatically analyzes inspection images to detect and classify defects, significantly improving speed and accuracy compared with conventional methods that rely on human judgment.
