OCT for NDT of 3D additive printing

Manufacturing

OCT is an excellent tool for evaluation of shapes and dimensions of tools, molds, and final parts, as shown here for polymer-based 3D printing. It can also provide real-time process feedback for control of ablation depth during laser machining, and for defect detection and dimensional analysis in additive manufacturing.





Aviation and Automotive

OCT can be used to evaluate application of critical coatings and paints in industries like aviation and automotive. High resolution layer imaging enables analysis of thickness uniformity and defects that can impact quality and safety, as shown in this detailed image of a multilayer paint coating.



Displays and Panels

The excellent axial resolution of OCT is ideal for imaging the multilayered structures used in display panels. The 3D information acquired can be used to evaluate flatness uniformity and identify subsurface defects affecting display quality. Sublayers < 10 µm in thickness can be clearly imaged, as shown here.



OCT for NDT of contact lenses

Medical Devices

The medical industry has been quick to adopt OCT for the analysis of high precision medical devices due to its ability to generate non-contact images of very small, thin, and delicate structures such as this contact lens. OCT can also provides information about pores, defects, and gaps in the production of critical membranes and seals.

Corrective Lenses 

This high-resolution image of a contact lens edge taken with a  Cobra 800 OCT spectrometer shows the potential of OCT for material inspection. Contact lens edges are a feature of interest because comfort of a contact lens depends on how the lens contacts the cornea. No adequate non-destructive method exists for evaluation except OCT.

In this case, a tumor was implanted in the mouse ear to demonstrate the ability of OCT angiography to distinguish tumor margins. This technique is of particular interest in cancer and carcinoma treatment. It can also be applied in endocrinological diseases like diabetes, in which there is a need to study perfusion in the body.
