Non-Destructive Inspection Methods for LEDs Using Real-Time Displaying Optical Coherence Tomography
In this study, we report the applicability of two different Optical Coherence Tomography (OCT) technologies for inspecting Light Emitting Diode (LED) structures. Sectional images of a LED were captured using a Spectral Domain OCT (SD-OCT) system and a Swept Source OCT (SS-OCT) system. Their center wavelengths are 850 and 1,310 nm, respectively. We acquired cross-sectional two dimensional (2D) i...
متن کاملOptical Coherence Tomography – Applications in Non-Destructive Testing and Evaluation
The field of non-destructive testing and evaluation (NDTE) comprises many different techniques and approaches. Over the past few decades there have been tremendous ad‐ vances in NDTE technology, allowing researchers and engineers to tackle problems in many scientific and industrial fields. However, techniques enabling a fast, contactless, non-invasive, and high-resolution imaging of subsurface ...
متن کاملReal-time multi-functional optical coherence tomography.
We demonstrate real-time acquisition, processing, and display of tissue structure, birefringence, and blood flow in a multi-functional optical coherence tomography (MF-OCT) system. This is accomplished by efficient data processing of the phase-resolved inteference patterns without dedicated hardware or extensive modification to the high-speed fiber-based OCT system. The system acquires images o...
متن کاملThree-dimensional non-destructive optical evaluation of laser-processing performance using optical coherence tomography.
We demonstrate the use of optical coherence tomography (OCT) as a non-destructive diagnostic tool for evaluating laser-processing performance by imaging the features of a pit and a rim. A pit formed on a material at different laser-processing conditions is imaged using both a conventional scanning electron microscope (SEM) and OCT. Then using corresponding images, the geometrical characteristic...
متن کاملNon-destructive Inspection of Anti-corrosion Protective Coatings Using Optical Coherent Tomography
Optical Coherence Tomography (OCT) is one of the most rapidly advancing techniques. This method is capable of non-contact and non-destructive investigation of the inner structure of a broad range of materials. Compared with other methods which belong to the NDE/NDT group (Non-Destructive Evaluation/Non-Destructive Testing methods), OCT is capable of a broad range of scattering material structur...
