Optical coherence tomography (OCT) is a fundamentally new type of optical imaging modality. OCT performs high resolution, cross-sectional tomographic imaging of the internal microstructure in materials and biological systems by measuring the echo time delay and magnitude of backscattered light. I Image resolutions of 1-15 um can be achieved, one to two orders of magnitude higher than conventional ultrasound. Imaging can be performed in situ and in real time. The unique features of this technology enable a broad range of research and clinical applications. OCR imaging has its roots in ultrafast optics and draws upon many optical technologies including white light interferometry, fiber optics, and Fourier transform spectrometry.
