Patent ID: 7663757

Claim:
A method for obtaining a reflectance property indication of a sample, wherein the sample is comprised of a lignocellulosic material, the method comprising: (a) providing an optical reflectometer; (b) relatively positioning the sample and the reflectometer; (c) making a reflectance measurement of the sample with the reflectometer, wherein the reflectance measurement represents an observed reflectance of the sample; and (d) correcting the reflectance measurement in order to obtain the reflectance property indication, wherein the reflectance property indication represents a standardized reflectance of the sample, wherein correcting the reflectance measurement accounts for a difference between the standardized reflectance of the sample and the observed reflectance of the sample, and wherein correcting the reflectance measurement is comprised of making a correction selected from the group of corrections consisting of a geometry correction, a texture correction, a drift correction, and combinations thereof.
