In Greek hólos means whole and grafē means writing or drawing and hence the word Holography. The holographic technique is exactly what its etymology implies – making of the whole image.  In simple words holographic technique allows the light scattered from an object to be recorded and later to be reproduced so that the image of the object is recreated at exactly the same reference relative to the recording medium. This invention was made in 1947, by a Hungarian – British Physicist Dennis Gabor, He later on went on to win the Nobel for this discovery in 1971. The invention of laser made holography a happening technology. There are different kinds of Holographic techniques. These techniques vary in the method of recording the image, and also in the later reproduction of that image. Some of the relatively popular holographic techniques are Transmission holography, Rainbow transmission holography, Denisyuk holography, Specular Holography and Lenticular Holography. Holography uses ...
