Abstract
The present invention relates to probe apparatuses and component combinations thereof that are used to recognize possibly abnormal living tissue using a detected early increase in microvascular blood supply and corresponding applications. In one embodiment there is disclosed an apparatus that emits broadband light obtained from a light source onto microvasculature of tissue disposed within a human body and receives interacted light that is obtained from interaction of the broadband light with the microvasculature for transmission to a receiver. Different further embodiments include combinations of optical fibers, polarizers and lenses that assist in the selection of a predetermined depth profile of interacted light. In another embodiment, a kit apparatus is described that has various probe tips and/or light transmission elements that provide for various combinations of predetermined depth profiles of interacted light. In a further embodiment, a method of making a spectral data probe for a depth range detection selectivity for detection of blood within microvasculature of tissue is described.
