An embedded, nondestructive apparatus and methodology has been developed for armor composed of glass layers. The technique and apparatus were developed because the only previous system of inspection required the use of a high-power X-ray machine. This was expensive and usually not available in theater. The technique presented in this paper uses off-the-shelf components and a rather simple algorithm, which does not require extensive computation. LEDS were used for light generation, and photo- transistors were used to measure the amount of light transmitted. The apparatus is installed when the armor is manufactured, before it is encased in a box. The system output is presented in a simple, easy-to-use format, which tells the user if the armor cube is healthy or damaged. If damage has occurred, the user is informed of which layers in the cube are damaged. In this case, the spectrum of tight was in the visible band, though it need not be since infrared photo-detectors could also be used.
