ABSTRACT:
The invention relates to a method and device for analyzing a tissue (70), which comprises: —irradiating the tissue (70) with light focused on a focal region (40); —collecting light coming back from the focal region (40) into a first detection device (100A), the first detection device (100A) being arranged to only collect the light coming back from the focal region (40), on a first detection area (140A), by confocal spectroscopy, in order to generate a first signal, containing information on an optical property of the tissue (70); —collecting light, scattered from the focal region (40) to at least a second region (60), coming back from the second region (60), into a second detection device (100B), the second detection device (100B) being arranged to only collect the light coming back from the second region (60), on a second detection area (140B), in order to generate a second signal, —using the first and second signals in order to get information on the scattering and/or absorption coefficients of the tissue (70) in the region between the focal region (40) and the second region (60). Thanks to the invention, information can be gathered on the scattering and/or absorption properties of the tissue.
