1. An optical imaging apparatus comprising a lighting system to illuminate a point of a target and generate at least one multiply scattered light component and a directly scattered light component in response to the illumination, a positioning element for varying the point of the target illuminated by the lighting device among a plurality of points of the target, a separation device to isolate the directly scattered light component and different ones of said multiply scattered light components from each other, a detection system to detect at least substantially simultaneously the directly scattered light component and the at least one multiply scattered light component, and a processor for generating a first set of image information from the directly scattered light component and a second set of image information from the at least one multiply scattered light component.
