What is Holograph?

Bypassing the time, science is being fast and fast. By the inventions of the latest technologies day by day, the creation is surprised. New incidents are happening in technologies which surprise the whole world. New surprising technology is introduced by each coming time, which become a part of our life and become an essential part of our life. The scientist has claimed at the present time that they could meet your later peoples. The people who have died, scientists could meet you with your dead dears. This is unbelievable but the technology is being too fast to be explained. This is possible at present. This is possible with the latest technology, known as holography. We only can see the object in the presence of light. An object cannot be seen without the presence of light. The light is applied on the object and the light is reflected towards our eyes then we can understand the object because the thought of that image already existed in our mind. Keeping this same phenomenon, the scientist has invented holographic technology. The American company portal INC. has claimed that they have developed a box-like phone booth, by which we can see and talk like real to our dears who died. It’s like we record our voice on cell phones and listen. We store our voice and then we listen to it later again and again when we need it. Similarly, the scientists thought the object must also be stored for future memories and uses. It could be possible only with the holography. The scientist thought that if a voice could be stored for the future, then why we cannot store the light and objects. They thought about this and worked for this and finally, they succeeded. The word “Holography” is derived from the Greek word “Holograma” which means the message received from away. In another one, holography meaning in Greek Holos (whole) and graphe (writing or drawing). It was discovered by a Hungarian scientist Dennis Gabor in 1940. Later, he was awarded a Nobel Prize due to enhancement in holography technology in 1971. The first optical holography practical was enabled by laser to record 3D (Three Dimensional) objects in 1962. The first exhibition of this technology was held in London. In this exhibition, some wild animals and astronauts were presented with the help of holography technology. With the help of this technology, a barren land can be shown into fertile land, or fertile land can be shown into the barren land, or heaven into hell while a hell into heaven. Let us know how this technology works, first of all, a 3D video is recorded of the object which needs to be shown, then this video is played into 7D technology. It looks like a real image. In this technology, a video is separated into six pieces. Then, with the help of a laser light device, these six pieces are shown in the form of a video. These laser light waves are emitted and put on a particular point from whole sides i.e. left, right, up, down, to and fro. When these waves of light are focused on a particular point and completed, then an object is created to look like a real image after focusing on a point. This is performed in a room or cabin so that all laser waved might be focused on a fixed point. To enhance and upgrade in this technology, scientists from the USA, UK and Israel are working. The holograph of the USA president has been made present in his digital library. It was claimed that the holograph of several USA Army soldiers to get meet his family and this experience was successful. Further, many couples were got met with one another in the days of COVID-19. By using this technology, the customer will feel a reality while conversing with anyone. They will be looked like real and talking physically even their body language could also be seen. This will look like a real phenomenon. In the future, this technology could be used in museums. With the help of this technology, the visitors may put questions to any historical personality. However, scientists agree with this technology has a lot of disadvantages as compared to advantages. This technology is used as a detective. Even the maps of the cities of any country could be changed. Different T.V channels have this technology and by using this technology then can find any person wandering in the world, in their studios and seems to look like a real personality is talking in front of them. This technology has been used in many Hollywood movies. In this technology the object is put in front of the mirror and laser light is applied at every angle then it is recorded and presented by laser light beams. In the future, the holography will have the glory and would be used for sky graphic and space graphic and would be presented before the world. With the help of this technology, the people will be shown very strange scenes in front of them in the sky and this work is in progress and with the passage of time the projections of many different things like animals, ruins are shown to the people with sky graphic. Upcoming time, with this technology the whole world will be globalized. The future will decide the advantage and disadvantages of this technology. How would this technology affect human lives and in other fields? No doubt, there will be a revolution in the field of technology but this will also ruin the human lifestyle.
