Abstract (en)
[origin: WO2009033220A1] A method of identifying a material type of a surface includes directing a beam of light at the surface. A beam of light reflected from the surface is received and the intensity of the reflected beam measured to derive intensity data. An identification of the material is made based on the intensity data.
