Applications of metrology for optical coherence tomography

Optical coherence tomography (OCT) is a novel technique that has recently emerged as a promising biomedical imaging modality in ophthalmology, cardiology, oncology and a number of other medical disciplines. Basic contrast mechanism for OCT is gradient in refractive index of tissue constituents. Additional contrast mechanisms include Doppler, polarization and phase-sensitive imaging modalities. Applications of metrology include high-resolution spectrum analyzers for spectral domain OCT instrumentation development and characterization of refractive index of tissue constituents.
