Abstract
An apparatus and method is provided for identifying a diffusely-reflecting material, such as a textile fabric. A light source transmits radiation onto the unknown material, and a detector receives radiation diffusely reflected by the unknown material, and generates signals indicative of diffuse-reflection characteristics of the unknown material. A processor is coupled to the detector, and includes diffuse-reflection data on a plurality of reference materials. The processor compares 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.
