Holography is a technique that enables 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.

Mar 13, 2025 · 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 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.

Jun 28, 2020 · Holography is the technique of producing a three-dimensional image of an object. The photograph showing the three-dimensional image is called a hologram. After study how does holography work we have seen that there are many applications of holography?

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.

Aug 30, 2023 · Scientists can use holograms to study objects in three dimensions, and they can use acoustical holography to create three-dimensional reconstructions of sound waves. Holographic memory has also become an increasingly common method of storing large amounts of data in a very small space.

Holography is a class of methods for recording and reconstructing three-dimensional images, which are based on interference phenomena. Holographic images are called holograms. Unlike normal photographic images, they do not use a mapping of individual objects points to individual points in the hologram; in that sense, they are not images ...

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.

Key topics include the theory of holography, focusing on recording and reconstructing three-dimensional images through interference and diffraction of light. Research often explores different types of holography, such as digital, analog, and computer-generated holography, each offering unique methods for capturing and displaying holographic images.

Holography. Holography is similar to the photography technique, in which we can construct a 3-dimensional image of an object using a laser beam. That image is called as a Hologram. In this hologram we can see the front, side and top etc., portions of the object, similar to what we see in video games (or) 3D-films. Types of holographic techniques
