Abstract
A fiber instrument for measuring properties of a fiber sample, the fiber instrument having a surface for receiving the fiber sample, a hand for pressing the fiber sample against the surface, an illumination source for selectively illuminating the fiber sample with more than one peak wavelength, where each of the peak wavelengths is independently controllable as to an applied intensity of the peak wavelength, a sensor for capturing images of the fiber sample while it is illuminated, and a controller for controlling at least the sensor and the illumination source. By providing multiple peak wavelengths of illumination that are each independently controllable as to illumination intensity, the fiber instrument as described herein is better able to detect both foreign material within the fiber sample, and color gradations of the fiber sample.
