The holographic principle is an emerging notion within physics that the universe we know could be viewed as holographic. A hologram is essentially a means of storing the information for a system in a form that exists a dimension lower, like a 3D image projected from a 2D film.

El principal objetivo de esta cinta espantapájaros es ahuyentar a las aves para que no se acerquen a los árboles frutales y no destruyan su cosecha. Esta cinta ahuyenta las aves tanto por sonido como por luz. Las aves se asustan con el ruido metálico que produce [la cinta] al moverse con el viento. Por otro lado, la cinta refleja la luz, produciendo unos reflejos y sombras que asustan a las aves.

With the D-HUD, a form of holographic recording is used to produce a thin-film lens, covering the whole area of the curved combining glass.(...) This thin-film lens is produced by the use of a laser which records, photographically, a form of diffraction grating within a layer of gelatin which is coated onto the curved combining glass. After processing, the thin film lens is covered by a second glass layer to form a sandwich, with the "lens" formed by changes in the refractive index of the gelatin layer, providing the effect of a diffraction grating.

Ce nouveau collimateur fait appel à une forme d'enregistrement holographique qui crée une lentille à couche mince recouvrant toute la surface de l'optique de mélange. (...) Cette lentille à couche mince est créée par un laser qui enregistre photographiquement une sorte de réseau de diffraction dans une couche de gélatine appliquée sur l'optique de mélange, elle-même recouverte d'une seconde couche de verre formant sandwich.
