Paper Abstract

The optical coherence tomography images are useful to see the internal profile and the structure of material samples. In this work, OCT images were recorded in 10 volunteers with different skin tone which were related to Raman spectra. The areas where we obtained OCT images and Raman spectra were a) index finger nail, b) between index finger and middle finger, c) middle finger tip, d) half of middle finger, e) the thumb finger tip and f) between index finger and thumb, areas measured were for the purpose of finding extracellular fluids with contain triglycerides, cholesterol and glucose that are reported in the literature. The excitation wavelength used for this work was 785 nm, a spectrometer of 6 cm-1 resolution. The spectral region used ranges from 300 to 1800 cm-1. We use an OCT with 930 nm of Central Wavelength, 1.6 mm of Image Depth, 6 mm of image width and 6.2 μm of axial resolution.
