Electronic speckle pattern interferometry (ESPI), [1] also known as TV holography, is a technique that uses laser light, together with video detection, recording and processing, to visualise static and dynamic displacements of components with optically rough surfaces. The visualisation is in the form of fringes on the image, where each fringe ...
A holographic image can also be obtained using a different laser beam configuration to the original recording object beam, but the reconstructed image will not match the original exactly. [2]: Section 2.3 When a laser is used to reconstruct the hologram, the image is speckled just as the original image will have been. This can be a major ...
The AdS/CFT correspondence is often described as a "holographic duality" because this relationship between the two theories is similar to the relationship between a three-dimensional object and its image as a hologram. [25] Although a hologram is two-dimensional, it encodes information about all three dimensions of the object it represents.
Holography is the science of producing holograms; it is an advanced form of photography that allows an image to be recorded in three dimensions. Subcategories This category has the following 4 subcategories, out of 4 total.
Digital holography is the acquisition and processing of holograms with a digital sensor array, [1] [2] typically a CCD camera or a similar device. Image rendering, or reconstruction of object data is performed numerically from digitized interferograms. Digital holography offers a means of measuring optical phase data and typically delivers ...
Functional Holography (FH) is a method of analysis designed to extract the maximum amount of functional information about the dynamical network as a whole unit. Itay Baruchi and his Ph.D. supervisor, Eshel Ben-Jacob , introduced the Functional Holography (FH) methodology.
Nevertheless, the lower limit over the grating spacing is one order of magnitude smaller than the latter. Their availability, low cost, and versatility opened the path for their use in a various range of applications such as data storage, [3] holographic display [4] [5] and in general, as holographic optical components.
