Because spatial frequency domain imaging (SFDI) can “see beyond” what the eye can see, we can capture a true assessment of underlying skin health. Many factors — melanin, epidermal thickness, collagen structure, hydration, and blood distribution — contribute to skin health and appearance. Our subsurface imaging allows us to quantify these components even before they are visible to help in skin assessment research.
We use structured illumination to take several snapshots with various patterns and colors, and then apply our advanced algorithms to combine these images and make it easy to understand the results. Our method measures a wide field of view and corrects for surface topology across all body areas, even the contours of a face (e.g., Balu et al., 2013; Gioux et al., 2009).
