ABSTRACT:
Devices, systems and methods for detecting surface characteristics of a sample surface are disclosed. The exemplary system may have a conveying device for moving a sample surface and a light source for reflecting a beam of light off the sample surface. A light detector may receive the beam of light reflected from the sample surface. The area of the beam of light may be unequal to an area of a light detection surface of the light detector. A reference analyzer may determine the optical surface based on a comparison of the reflected light received with known reflected light values for known sample surfaces.
