Optical Coherence Tomography (OCT)

What Is Optical Coherence Tomography?

Optical Coherence Tomography (OCT) is a technology for non-invasive optical imaging of tissue. This cross-sectional image is also referred to as tomography.

OCT is widely adopted within eye care where it is the gold standard for in vivo imaging of the retina. The eye specialist can perform non-invasive optical biopsies using the OCT technique. This allows the doctor to see a cross-section of the retina of the eye where the sharp vision is formed. Full 3D wide-field OCT scans have the potential to become a comprehensive tool for mapping out all the layers of the eye with better results in diagnosis and treatment.

OCTLIGHT´s Caliper technology has the following features and benefits with Ophthalmic OCT

  • Center wavelength of 1060 nm for deeper penetration into the eye (choroid imaging)
  • High sweep rates for wide-field, video-rate, and high-resolution 3D imaging
  • Long imaging range by its inherently long coherence length of more than 50 mm
  • Less constraints on sample positioning and simplified design of scanning equipment
  • Better sweep stability enabling high-quality imaging and phase-sensitive OCT (e.g., angiography)
