1. A method comprising:

  • providing a segment of optical fiber comprising a first end face, a second end face, and a cylindrical surface extending from the first end face to the second end face;

    forming refractive index disruptions within a volume defined by the first end face, the second end face, and the cylindrical surface in response to illuminating the segment of optical fiber with actinic radiation;

    generating a laser interference pattern from the formed refractive index disruptions;

    reading the laser interference pattern through the cylindrical surface with a camera; and

    determining a code based on the read laser interference pattern.
