Patent ID: 7840360

Claim:
A system for non-invasively inspecting vessels comprising: (a) a near-infrared (NIR) imaging means comprised of a detector array and one or more lenses disposed adjacent thereto for taking an NIR image of the vessels; (b) one or more NIR light sources disposed opposite the NIR imaging means for illuminating the vessels; (c) one or more diffuser plates disposed adjacent the one or more NIR light sources; (d) an optical wavelength selecting means capable selecting a wavelength to be transmitted therethrough, said optical wavelength selecting means being disposed between the one or more lenses and the vessels, between the detector array and the one or more lenses, or between the one or more light sources and the vessels; (e) a computer processing means in communication with the NIR imaging means; and (f) a computer readable database in communication with the computer processing means, said computer readable database comprising absorbance IR spectroscopic data corresponding to water based and organic based liquids.
