What is optical holography?

Optical holography is a different type of display where the end result is often referred to as a hologram. With this type of display, light is recorded according to accurate amplitude and also how it is reflected by the selection of the object that has been photographed. In optical holography, the completed result is represented as a three -dimensional (3D) image. Scientists also considered its use in X -ray technology. In addition to its more practical use, optical holography is often used in entertainment places such as stage presentations, community fairs and entertainment parks. Since this imaging science began to evolve at the end of the 1940s and has reached almost perfection at the age of 60. Such uses include small holographic images or seals used to strengthen documents, images used in design presentations, holographic recreations used in science and technology, and three -dimensional images that are used exclusivelyfor the purposes of entertainment.

When creating optical holography, laser light must be divided in such a way as to create two separate light rays. Using special equipment and film, one beam is used to throw the light into the object, while the other beam is used to link to the object. When they both integrate again, a hologram creates and appears as a three -dimensional image.

Since her work in 1948, Dennis Gabor Holography gave birth to a number of different types of holographic imaging. He is even responsible for the non -optical type of well -known acoustic holography, which includes reconstruction and reconstruction of sound waves. All types of holography rely on the use of interferogram, which is deliberate interference of light waves that produce light and dark patterns as they are.

While optical holography has significant scientific, teaching and entertaining use, scientists continueKtical applications. One such application involves the use of optical holography techniques to detect deficiencies in objects and surfaces. For example, deformities and other deficiencies in defensive structures such as aircraft, missiles and submarines may not be visible to the mere eye. However, using optical holography engineers are able to find damaged tools and parts. In the commercial aviation industry, it is increasingly used to check aircraft vehicles to determine whether invisible cracks and other damage are present on any part of the aircraft.
