    Visualization of Blood Vessels Using Optical Coherence Tomography

    New methods of optical coherence tomography (OCT) have been developed. OCT is a modern technique for noninvasive in vivo examination of upper layers of human skin and subcutaneous blood vessels using nonionizing radiation. The instruments described in this work use a low-power (0.2–0.4 mW) superluminescent diode. Several wavelengths can be applied simultaneously. Raster scanning and raster averaging in the interferometer sample arm increase the signal-to-noise ratio by 4–10 dB.
