Abstract
Non-invasive optical detection devices and techniques that use optically discriminative detection of returned probe light from a target by spatially separating the returned probe light from the deep tissue structure and the returned probe light from the skin surface and the shallow tissue structure based on different wave vector components to improve the optical detection sensitivity in detecting the returned probe light from the deep tissue structure with reduced optical interference by the returned probe light form the skin surface and the shallow tissue structure.
