Optical Coherence Tomography

Optical coherence tomography (OCT) is a non-contact imaging technique employing near-infrared light of short coherence length, through the use of an interferometer, for tomographic inspection of scattering materials. The purely optical scattering-based evaluation allows the investigation of various materials with high spatial resolution in the micrometer range.


  • Imaging spectroscopy method
  • Non-contact, non-destructive measurement
  • Backscattering technique, access from only one side necessary
  • Spatial resolution up to 3μm (voxel size)
  • High measuring frequencies, live imaging possible, inline capable
  • No ionizing radiation
  • Compact and robust design
  • Variable measuring field
