Optical Coherence Tomography (OCT) applications
Advancing imaging for healthcare and industrial insight
Optical Coherence Tomography (OCT) has revolutionized imaging in medicine, manufacturing, and research by offering non-invasive, high-resolution visualization beneath surfaces and within biological tissue. Central to the success of OCT systems are spectrometers that deliver fast acquisition speeds, high sensitivity, and exceptional resolution—allowing for real-time, detailed insights across a range of applications.
From ophthalmology and cardiovascular diagnostics to precision material inspection, compact and reliable OEM spectrometer solutions continue to drive innovation and enable advanced imaging capabilities across industries.
What characterizes applications of OCT?
Optical Coherence Tomography (OCT) is best suited for applications requiring micron-level resolution and subsurface imaging in a non-contact, non-destructive format. Systems typically offer:
- Axial Resolution: Ranges between 1–15 µm, depending on the spectral bandwidth and central wavelength used.
- Imaging Depth: Typically between 1–3 mm in biological tissue and up to 10 mm in optically transparent or scattering industrial materials.
- Lateral Resolution: Often 10–20 µm, influenced by focusing optics and system design.
OCT works well for real-time diagnostics and process monitoring requiring high-speed acquisition of thousands of scans per second. Materials where OCT is most effective are low-scattering, semi-transparent, or layered materials, including:
- Biological tissues (e.g. retina, skin, vascular tissue)
- Polymers and plastics
- Ceramics
- Glass
- Silicon wafers and photonic components
Common application demands include:
- Depth-resolved structural analysis: Capturing layered microstructures without physical cross-sectioning.
- Surface and subsurface defect detection: In components like adhesives, composites, and optical coatings.
- Compact system integration: OCT’s scalable design enables deployment in portable medical devices, robotic inspection systems, and lab-on-chip instruments.
If your use case involves sub-millimeter scale imaging, non-invasive measurement, or layered media evaluation, OCT is likely a strong fit.
Examples of OCT applications
Ophthalmology
Ophthalmology is one of the most established applicatiions for Optical Coherence Tomography (OCT). OCT provides high-resolution, cross-sectional imaging of the retina and anterior segment, offering axial resolutions down to 1–5 µm and imaging depths of up to 2–3 mm. These capabilities make it indispensable for diagnosing and monitoring conditions such as macular degeneration, glaucoma, and diabetic retinopathy, where detecting subtle structural changes is critical. Its non-invasive, real-time nature allows clinicians to assess ocular health with exceptional precision and patient comfort.
Cardiovascular diagnostics
Cardiovascular diagnostics play a crucial role in detecting, evaluating, and managing heart-related conditions. Optical Coherence Tomography (OCT) is offering a new level of precision in assessing vascular health. This advanced imaging technique delivers micrometer-resolution cross-sectional views of coronary arteries, allowing clinicians to detect subtle plaque morphology, microvascular damage, and stent placement outcomes in real time. Unlike traditional imaging modalities, OCT’s ability to visualize tissue microstructures within arteries elevates its value for diagnosing atherosclerosis, planning angioplasty, and monitoring interventional success.
Monitoring of coating layers
Optical Coherence Tomography (OCT) has found a powerful niche in industrial applications, particularly for monitoring coating layers in manufacturing processes. With its ability to provide non-contact, real-time, high-resolution cross-sectional imaging, OCT enables precise measurement of layer thickness, uniformity, and detection of defects or delamination in materials like paints, polymers, and protective coatings. This makes it a vital tool for quality assurance in industries such as automotive, electronics, and pharmaceuticals, where tight tolerances and consistent performance are crucial. Its speed and sensitivity help optimize production, reduce waste, and ensure product integrity.
Dermatology and Tissue Imaging
In dermatology and tissue imaging, Optical Coherence Tomography (OCT) offers a powerful, non-invasive way to visualize subsurface skin structures in real time. It provides micrometer-resolution cross-sectional images that allow clinicians to assess epidermal and dermal layers, detect abnormalities like basal cell carcinoma, and monitor wound healing processes with exceptional precision. Because OCT operates without the need for biopsy, it has become a valuable tool for diagnosing and managing skin conditions more comfortably and efficiently for patients.
