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. The charge coupled device camera has an array of pixels which receive the reflected light pulse. Pixels receiving the reflected light pulse at an intensity 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. A prism focuses the reflected light pulse received by the second and third photo diodes, and a transparent block encloses the strobing Xenon bulb and the first photo diode so that the light pulse is conducted from the Xenon bulb to the first diode. Processing means analyze the color signal and the reflection signal and produce a composite value, and a percentage value representing the percentage of dark pixels in the array of dark and light pixels. Furthermore, the processing means recognizes and classifies patterns of dark pixels in the array of light and dark pixels, and controls fiber processing equipment in response to the composite and percentage values.
