Holmium

== Description ==
A rare-earth metallic element. Holmium occurs naturally in rare-earth minerals such as gadolinite, monazite, and xenotime. Its abundance in the earth's crust is about 1.2 ppm. Holmium was discovered by Delafontaine and Soret in 1878 and independently by Cleve in 1879. Metallic holmium is a silver gray color and tarnishes slowly in air. Holmium is used as a catalyst and for some electronic applications.

Hologram

== Description ==
A three-dimensional image created by holography. A hologram is created by exposing a negative image with monochromatic radiation from a laser while it is positioned in a second laser beam. The direct beam and the image scattered beam combine to form an interference pattern that is viewed as a three-dimensional image. The technique for making holograms was invented in 1947 by Dennis Gabor of Hungary, but was not widely used until after the laser was invented in 1960. Salvador Dali used holography to make works of art.

Holographic interferometry

==Description==
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). These measurements can be applied to stress, strain and vibration analysis, as well as to non-destructive testing and radiation dosimetry

Holography

== Description ==
Holography is a technique that allows the light scattered from an object to be recorded and later reconstructed so that when an imaging system (a camera or an eye) is placed in the reconstructed beam, an image of the object will be seen even when the object is no longer present (cf Wikipedia).
As a non destructive testing method, holography consists in visualising the interference image between the image of a still object (with no constraint) and the image of the same object supporting a mechanical constraint, which can be induced by a mechanical force, a heat source, or a pressure modification. This method permits to detect delaminations, unbondings, etc.
