Abstract: A supply chain monitoring system having a laser-based image system usable within an object processing facility to form images in objects, a reader operable to read the images on the objects, and an object tracking system coupled to the reader over a data network. The laser-based image system includes an image forming device operable to form an array of laser-treated regions in the objects in single shot events, where the arrays of laser-treated regions are associated with images.

Abstract: A laser head uses nitrogen gas to provide output in the far ultraviolet region of radiation. The laser is supplied from an energization system including low voltage and high voltage sections. The low voltage section is supplied from a low d-c voltage, stepped up over a transformer and applied as pulses to a high voltage section, including a voltage doubler circuit. The doubler circuit includes two diode assemblies, and this circuit provides the high voltage pulses for energizing the laser head when a spark gap breaks down. The opposed electrodes of the laser head each have a serrated edge, and the serrated edges face each other to effect a pre-ionization of the gap between the electrodes. A capacitor, coupled across the laser head electrodes, has a particular construction to withstand the repeated, very rapid discharges occasioned for firing the laser, and this capacitor contributes to a laser construction which is truly portable.

Abstract: A laser head is constructed with a three-plate capacitor wrapped around the head. The capacitor plates are triangulated to assist in beam formation. The power supply is a resonant charge circuit, with a switch arrangement for regulating the extent of charge accumulated before the laser is fired, and the firing is regulated by another switch. The entire system is compact and constructed to utilize laser heads of different diameters, without changing the power supply or other components of the system.
