Optical coherence tomography for medical metrology
Optical coherence tomography (OCT) is a non-contact imaging method that is well-suited for tomographic imaging of semitransparent materials and tissues. The technology is based on detecting the optical echo reflected by fine changes in structures or diffraction indices. It allows for high-resolution, cross-sectional imaging with a depth of up to 3 millimeters. We have developed a custom OCT system that operates in the near-infrared spectral range. As a result of the modular architecture of the fiber-optic-based system, a technology transfer to various medical metrology applications is possible. The LSE team has developed automatic recognition software based on image processing algorithms to measure defects and layer structures within the tissue. In close collaboration with several university hospitals, in vitro studies have been conducted on the early detection of osteoarthritis.
