Each edge of each aperture includes a plurality segments forming a serrated edge, resulting in mixed edge diffraction. The apertures may be in an irregular and non-symmetric pattern and may be of variable size. A random diffusing layer may be in proximity to or integral with the substrate layer. The grayscale mask may be used for generating an optical element by printing the initial grayscale mask onto a photoresist layer and transferring the photoresist pattern onto a transparent layer and the mask may include areas or layers of variable transmission. Also described are methods for diffractive intensity averaging, diffractive error diffusion, diffractive spatial dithering, and diffractive intensity averaging.

摘要： A firearm comprising a gun barrel for accommodating a desired round of ammunition having a bullet, a shell casing and a primer. The gun barrel has a firing pin associated with a chamber of the gun barrel and the firing pin is activated by a trigger assembly. When the firing pin is activated by the trigger assembly, a striking surface of the firing pin strikes the primer and discharges the round of ammunition to propel the bullet out of the opposite end of the gun barrel. The firing pin, the interior surface of the barrel, or some other surface which contacts the shell casing carries a unique identifying indicia. Upon discharge of the round of ammunition, the component of the firearm carrying the unique identifying indicia transfers an impression of the unique identifying indicia to an exterior surface of the shell casing to identify that the shell casing was discharged by that firearm.

摘要： Aligning and testing alignment of optical elements in a laser beam delivery system using non-visible radiation. An alignment mirror replaces a beam redirection mirror and includes a fluorescing substrate and a dielectric coating on an incident face of the fluorescing substrate that reflects a major part of an incident laser beam along a next leg of the beam path and transmits a part of the beam into the fluorescing substrate, which is transmissive to visible radiation and fluoresces when irradiated by the beam to emit a visible light image from a back face of the alignment mirror. An alignment target on the back face indicates a preferred point of incidence of the beam on the alignment mirror for a desired alignment of the at least one laser beam. A lens may be tested and the properties of the lens determined by use of a fluorescing target plate.
