<p>An apparatus and method is provided for identifying a diffusely-reflecting material (F), such as a textile fabric. A light source (14, 114, 214) transmits radiation onto the unknown material, and a detector (24, 124, 224) receives radiation diffusely reflected by the unknown material, and generates signals indicative of diffuse-reflection characteristics of the unknown material. A processor (246) is coupled to the detector, and includes diffuse-reflection data on a plurality of reference materials. The processor (246) compares (342) the diffuse-reflection characteristics of the unknown material based on the signals of the detector to the reference data, and by a process of elimination, identifies the unknown material. <IMAGE></p> |
