1. A system for providing optical imaging in a medical diagnosis, comprising: at least one illuminating light source for generating light illuminating a portion of an object; at least one structured light source for providing a projection channel and projecting a structured light-pattern on the portion of the object; at least one camera for providing an imaging channel and imaging the portion of the object and the structured light pattern; and a computer, configured to: calculate by triangulation a three-dimensional topology of the portion of the object based on a correspondence established between the projection channel and the imaging channel; perform three-dimensional motion tracking based on the calculated three-dimensional topology; and generate a grade corresponding to a lesion of the object based on a multivariate analysis on temporal acetowhitening kinetics measurements performed on an area of the portion of the object corresponding to the lesion.
