A Study on Palaeobotany of Karanpura and Bokaro Coalfields

Any scientific concept or instrument discovered or invented by the scientists may be considered as a difficult subject till it is not presented in the simpler form . Besides, it is also a hurdle in the way of development. For example, photographic technique being presented in such a way that it became a part of life of the people all over the world. In photography a 2-dimensional image is formed. How surprising it will be if the image will be 3-dimensional and it may be seen in the air far from the surface, from all the directions. It is possible today. Due to the development of 3-dimensional photographic technique, known as Holography, it became true. In this paper, basic principles of holography, method of image recording of 3-dimensional image and its uses in modern life have been discussed.
