<p>The method involves directing light in a reflective optical component (2), from the light output side (8c) of the component, and passing into an image receiver (17). The light is diffracted between the light exit side and image receiver, so that a diffraction pattern (7) is generated. A prism sheet is used to generate the diffraction pattern. The light is reflected after diffraction of the light and prior to entering into the image receiver. An independent claim is included for verification system.</p> |
