Abstract
Apparatus, systems, and methods for the inspection of holes in transparent materials, the apparatus including a processor, an illumination probe, and a detection probe. The illumination probe includes a laser light source and a reflective surface and is configured to be inserted into a first hole in the transparent material. The detection probe includes a second reflective surface and a photodetector and is configured to be inserted in a second hole in the transparent material. Laser light is directed onto the first reflective surface within the first hole and is reflected through a wall of the first hole, into the transparent material, and reflected by the second reflective surface to the photodetector. The photodetector transmits a measured light intensity value to the processor, which compares the light intensity value to a standard intensity value to determine whether or not a crazing condition exists in the second hole.
