Embodiment Construction
[0029] For successful in vivo Raman spectroscopy measurements, the Raman system needs to include a filtering mechanism configured to minimize or eliminate background Raman and fluorescence signals from the fiber material and to be able to collect sufficient signal to This enables Raman spectra to be acquired within seconds or sub-seconds.
[0030] figure 1 An embodiment of a Raman system 10 is schematically shown. The Raman system 10 may include a probe 1 , a light source 2 , a spectrograph 3 and a detector 4 . The light source 2 may be capable of providing an figure 2 )) A monochromatic light source of excitation light that induces Raman scattering, such as a laser. Any other light source or combination of light sources that can provide excitation light to induce Raman scattering in a subject illuminated by the excitation light may be used. The light source 2 may be configured to minimize interference from undesired sources, for example, the light source may be selected ...
