  • Holography - Wikipedia
    Holography is a technique that allows a wavefront to be recorded and later reconstructed It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry
  • 4. 8: Holography - Physics LibreTexts
    Holography is the process of producing holograms and, although they are recorded on photographic film, the process is quite different from normal photography Holography uses light interference or wave optics, whereas normal photography uses geometric optics
  • Holography | Optics, 3D Imaging Laser Technology | Britannica
    Holography, means of creating a unique photographic image without the use of a lens The photographic recording of the image is called a hologram, which appears to be an unrecognizable pattern of stripes and whorls but which—when illuminated by coherent light, as by a laser beam—organizes the light
  • Holography - an overview | ScienceDirect Topics
    Holography captures the phase and amplitude of light reflected from, or transmitted through, an object In visual terms it captures ‘true’ three-dimensional space and any objects which are placed within that space
  • Holography – University Physics Volume 3
    Holography is the process of producing holograms and, although they are recorded on photographic film, the process is quite different from normal photography Holography uses light interference or wave optics, whereas normal photography uses geometric optics
  • Holography - HyperPhysics
    Holography is "lensless photography" in which an image is captured not as an image focused on film, but as an interference pattern at the film Typically, coherent light from a laser is reflected from an object and combined at the film with light from a reference beam
  • Different Types of Holograms – Holocenter
    There are a number of distinct types of art holograms that can be defined by their optical-geometry and the recording medium The Denisyuk Reflection Hologram A Denisyuk hologram is created with a ‘single’ beam’ of laser light that is shone through the hologram surface and then bounces off object back into the hologram surface
  • Introduction to Holography - ThoughtCo
    Holograms create three-dimensional images by using light interference patterns from laser beams Lasers make holograms because their light is coherent, meaning it has the same frequency and phase Holograms are used in arts, data storage, security, and were improved by lasers invented in 1960
  • Holographic Technology | Research Starters - EBSCO
    Unlike traditional photography, which captures two-dimensional images, holography records the light from an original scene, enabling the viewer to perceive depth and perspective as if they were observing the actual object
  • Holography - Nature
    Holography is the study of the use of light for storing and recreating three-dimensional data of objects This is typically done using interference and diffraction patterns to record phase
