Abstract
A structured-light imaging system includes a structured light projector for illuminating a surface and an electronic camera configured to image the surface. An image processor receives the images and has structured light scatteroscopy (SLS) firmware with machine readable instructions that illuminate the surface with structured light having a spatial frequency of at least 0.5 mm″1, and process the images to determine a map of scattering parameters at the surface independent of absorption properties. In an embodiment, the system also has cameras configured to obtain a stereo pair of images of the surface, the image processor having 3D firmware for extracting a three dimensional model of the surface from the stereo pair of images and compensating the map for non-flat surfaces.
