Optical Coherence Tomography (OCT)

OCT is used in many fields like medical and manufacturing, especially for non-destructive testing (NDT). OCT uses interference of low coherence light between a reference surface and an inspection object to construct a 3D multi-surface image of the object. Using this technology, multilayer surfaces can be imaged at high lateral and axial resolution.

At INO, we can use OCT for many applications such as:

• Surface  Profilometry:   Profile of clear coat, plus base coat can be measured simultaneously. Measurements are impervious to specular reflections, diffusive surfaces, changing lighting conditions, dust or aerosolized particles.
• Paint Layer Thickness:   Layer thickness is directly measured for all layers imaged with micrometer precision.
• Defect Detection: scratches, inclusions, dents and other defects can be measured and detected, and porosity can be characterized.

• Porosity: Surface porosity can be characterized.

• Metallic flake analysis: Quantification and distribution of metallic flakes in paint can be assessed.

Benefits from INO's OCT technology include real-time digital post processing (FPGA or GPU), high speed/MHz sampling rates, custom probe heads for large fields of view,  and systems for inspecting high aspect ratio or difficult access part or for use in hazardous environments.

You can also take advantage of a high-resolution 3D imaging over m² scale surfaces.
