    摘要: The invention relates to a method of recording machine-readable information on an article, including the steps of: providing a carrier having flakes dispersed therein onto the surface of the article, wherein all of the flakes have a beam-splitting grating pattern encoding the information thereon; aligning the flakes parallel to a sloped plane forming a slope angle with the surface of the article; and, solidifying the carrier. When the article is irradiated with an EM beam, a first portion of the EM beam is reflected from the surface of the article, forming a surface reflection, a second portion of the beam is reflected from the beam-splitting grating pattern, forming an arrangement of sub-beams, and the slope angle provides a spatial separation between the arrangement of sub-beams and the surface reflection, enabling machine-reading.

    摘要: An optical structure includes a light transmissive substrate having a surface relief pattern applied thereon, such as a hologram. A patterned layer of a reflective material is applied over portions of the surface relief pattern so as to form alphanumeric characters, bars codes, or pictorial or graphical designs. An optically active coating is applied over the patterned layer of reflective material and exposed portions of the surface relief pattern in order to provide desirable optical effects to the exposed portions of the surface relief pattern. In some embodiments, the optically active coating is a color shifting thin film, or contains color shifting flakes. Optionally, the material of the optically active coating is index matched to the light transmissive substrate in order to optically erase the effect of the surface relief pattern in the portions of the surface relief pattern not covered by the reflective material.
