Applications of holography University of Wisconsin–Madison
Download or Read Book Microwave and millimeter-wave non-destructive testing and evaluation (NDT&E) is generally understood to mean using high-frequency electromagnetic energy to inspect and characterize materials and structures.... Holographic interferometry is an experimental method that can be used in non-destructive testing (NDT)t. The principle is that the image of an object stored on holographic film is made to interfere with the real object or with another image stored on the same holographic film. This technique can be used for studying localized deformations arising from strain perturbations caused by the
Specialized techniques in holographic non-destructive
A cylindrical holographic stereogram with white light reconstruction, or a multiplex hologram can be conveniently used as a tool of non-destructive testing if the original picture is taken with X-rays.... Holographic interferometry (HI) is a technique which enables static and dynamic displacements of objects with optically rough surfaces to be measured to optical interferometric precision (i.e. to fractions of a wavelength of light).

Non-destructive testing apparatus may comprise a photon source and a source material that emits positrons in response to bombardment of the source material with photons.
- Perhaps the most promising application of holography is in the field of non-destructive testing. There are presently three basic types of non-destructive testing using holography, namely, the real time analysis method, the double exposure method, and the time averaging method. In real time holography, a single exposure of photographic plate is made of an object in equilibrium at a reference
