Abstract:
1. A method of analyzing a tissue, the method comprising acts of: irradiating the tissue with initial light focused on a focal region; collecting first light coming back from the focal region into a first detection device arranged to only collect the first light coming back from the focal region, on a first detection area by confocal spectroscopy to generate a first signal including information on an optical property of the tissue; collecting second light scattered from the focal region to at least a second region, coming back from the second region into a second detection device arranged to only collect the second light coming back from the second region on a second detection area to generate a second signal; and using the first and second signals to get information on the scattering and/or absorption coefficients of the tissue in the region between the focal region and the second region.
