Optical properties of tissues and tissue components are important parameters in biomedical optics. We report measurements of tissue refractive index n, and the attenuation coefficient p, using optical coherence tomography of individual vascular wall layers and plaque components. Moreover, since the temperature dependence of optical properties is widely known, we compared measurements at room and body temperatures. A decrease of n and p, was observed in all samples, with most profound effect on samples with high lipid content.
