A photograph, as a two-dimensional recording of an image formed by a lens, can be blurred from the start; the sharpness of the image is not affected by the light source used to illuminate it. The situation, however, is completely reversed for an optical hologram, which is a recording of a stationary quantum interference pattern, not an image. 2, record 1, English, - optical%20hologram

A structure feature is a security feature containing some form of verifiable information based on the physical construction of the feature. Examples include: the interference characteristic of a hologram or other optically variable device that can be uniquely identified by a suitable reader; retro-reflective images embedded within a security laminate; controlled transmission of light through selective areas of the substrate. 1, record 2, English, - structure%20feature

Un élément de structure est un élément de sécurisation contenant une forme d’informations vérifiables reposant sur sa construction physique. En voici quelques exemples : caractéristique d’interférence d’un hologramme ou de tout autre dispositif optique variable qui peut être identifié de façon spécifique par un appareil de lecture approprié; images rétroréfléchissantes incrustées dans un laminat de sécurité; transmission contrôlée de la lumière dans des zones particulières du support. 1, record 2, French, - %C3%A9l%C3%A9ment%20de%20structure

Au même titre que l'holographie optique, l'holographie acoustique vise à réaliser une image en trois dimensions. Le son est une vibration et possède les mêmes propriétés que la lumière quant aux interférences et à la diffraction. Il est donc possible de réaliser un hologramme acoustique. 1. Nature du son. Le son, comme la lumière, est une onde sinusoïdale. C'est un ébranlement périodique de l'air, une succession de pressions et de détentes. La fréquence fondamentale de la vibration définit la note. Par exemple, le la est à 440Hz. La plage de fréquences audibles s’étale de 20 Hz à 20 kHz. En dessous de 20 Hz, on parle d’infra-basses, et au-dessus de 20 kHz, d’ultrasons. 1, record 3, French, - vibration
