Abstract
Identifying a test product having a test region includes impinging on the test region a set of test signals at known test wavelengths. An image of the test region is generated from the reflected signals. The image is comprised of a set of reflectance values that are compared against reference reflectance values at the test signal wavelengths to determine the test product type.
