The Technology is the collection of techniques, methods or processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation.

Since 1946, when the first computer was created, the advance and development in the technologies has reached absolute limits.

 

Digitizing has supposed a revolution in the processing, storage and the changing of the information because it has reached several progresses like how to manage big quantities of information, to do copies and a fast exchanging between the users, the same as an easy access to it from any different part of the world, so on; it has  radically transformed the consumption habits and has offered a multitude new possibilities like telecommunications.

 

Holography is a technique which enables three-dimensional images (holograms) to be made. It involves the use of a laser, interference, diffraction, light intensity recording and suitable illumination of the recording. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object were still present, thus making the image appear three-dimensional.

 

It has got different applications like art, data storage, security, medicine… These holograms are also used in disciplines such as engineering , forensics , paleontology , archeology and natural science to dissect computer-simulated hurricanes.

 

For example, it has eventually been used in the USA where using a computer model, special glasses and a joystick (command or control) for cutting the body in 3D. Moreover, this technology can display muscle tissue , bone and various organs. This use of holograms of human body enables students to enlarge, shrink , zoom in and out each of the images, and back up and return to work in the body for further cuts.

 

As we have seen, technology will be an important part in our lifes, making them easier and more comfortable, and allowing us to develop holography because in the following years, it’s supposed to improve more than it does these days.
