What Are Some Applications Of Holography?
You will find holographic art in holography museums, advertising, postage stamps and jewelry. Holography is also used in security from forgery on credit cards, tickets, etc. In optical devices, holography is used in holographic lenses and diffraction gratings. These are holograms in which the object is a mirror or a lens. A flat mirror as an object produces a diffraction grating. A lensor uses a concave mirror as an object to produce a hologram that behaves like a lens. These holographic lenses are lighter than the traditional lenses and mirrors that can be designed to perform more specialized functions such as making the panel instruments of a car visible in the windshield for enhanced safety. Holographic interferometry is a very precise technique for measuring changes in the dimensions of an object. They are useful in industrial stress analysis and quality control. Pattern recognition uses electro optical devices with computer to interpret what is seen by a machine. Peace time and mi
