MARTINA MÜLLER AND MAREK KREHEL, 3D AG

As anti-counterfeiting features, holograms are present on various products, from banknotes and credit cards to children’s strollers. Most people encounter them every day, yet they are often unaware of their presence. Holograms are subject to continuous research and development and are more recently known in the form of projections. They are even considered futuristic art by some. The invention of holography tells a long story of research that is based on fundamental laws of physics and optics. Like photography, holography is a way of recording, yet the technologies have...Read full article

    holography
    Holography is a technique used to capture and reconstruct three-dimensional images using the principles of interference and diffraction of light. Unlike conventional photography, which records only the intensity of light, holography records both the intensity and phase information of light waves scattered from an object. This allows the faithful reproduction of the object's three-dimensional structure, including its depth, shape, and texture. The process of holography typically involves the...
