A fiber quality monitoring apparatus is constructed with a sample window for viewing a fiber sample. As the fiber sample passes the sample window, a bulb is strobed to produce a light pulse that is directed toward and reflected by the fiber sample. When the light pulse reaches a desired intensity, a first photo diode generates a synchronization signal. A second photo diode detects reflected light with a wavelength between about 500 nanometers and about 600 nanometers and produces a reflection signal. A third photo diode detects reflected light with a wavelength between about 430 nanometers and about 530 nanometers and produces a color signal. A charge coupled device camera is positioned to receive the reflected light pulse. Pixels below a desired value are designated as dark pixels and pixels receiving the reflected light pulse at an intensity greater than the desired level are designated as light pixels.
