Volumfaseholografiske

Volumfaseholografiske refers to a type of hologram where the recording medium is a volume material, as opposed to a thin surface. In this method, the interference pattern between the object beam and the reference beam is recorded throughout the depth of the holographic material. This three-dimensional recording leads to unique holographic properties.

When reconstructing the image from a volumfaseholografiske, light interacts with the entire volume of the recording. This interaction causes diffraction of the illuminating light, recreating the original wavefront of the object. The resulting image is characterized by its high fidelity and parallax, meaning that the perceived position of the object changes as the viewer moves their head, mimicking how we see real objects.

The thickness of the recording material is crucial in volumfaseholografiske. A thicker medium allows for a more complex interference pattern to be stored, leading to improved angular selectivity. This means that the hologram can be reconstructed efficiently by a narrow range of angles of the illuminating beam, which is advantageous for applications like holographic data storage.

These holograms are typically created using photosensitive materials like photopolymers or photorefractive crystals. The recording process involves exposing the material to the interference pattern, which alters its refractive index or absorption properties in a way that encodes the holographic information. Volumfaseholografiske have found applications in areas such as optical data storage, security features, and displays.
