Quantification of skin wrinkles using low coherence interferometry

摘要

We measure the skin wrinkle topology by means of low coherence interferometry (LCI), which forms the basis of the optical coherence tomography (OCT). The skin topology obtained using LCI and corresponding 2-D fast Fourier transform allow quantification of skin wrinkles. It took approximately 2 minutes to obtain 2.1 mm x 2.1 mm topological image with 4 μm and 16 μm resolutions in axial and transverse directions, respectively. Measurement examples show the particular case of skin contour change after -wrinkle cosmeceutical treatments and atopic dermatitis.
