Laser Holography For 3D View And Its Importance
Hello friends, in today's article I am going to tell you about laser holography. Before we talk about holograms or holography, we know how we can see them, because it is related to seeing. See, we can see something when light reflects on it and reaches us, without light we cannot see anything. If you go into a dark room, you will not see anything, you will feel as if you have become blind. Everything will look dark.Laser Holography |
Let me give you an example, you must have used a voice recorder ever, in that you say something and your voice is recorded. You can play it again and again later. Later, when it keeps on playing, then you keep on speaking for a while, it is the machine that plays. Means sound, vibration can be recorded and we know that we can see an object only because of light. Now here the question arises that can we keep the light also recorded like sound so that we can play it later and we will play the light later in that way then what is not there is there But it will appear again and again, so it is possible. This can happen in holography. In holography, suppose I am in front of you and walk away, then my recorded image can be shown in such a way, that too in 3D view, you will feel that I am standing in front of you, but in reality I will not be standing in front of you. could be possible.

Holography was invented in 1947 by a scientist named Dennis Gabor. It started further and better when the laser was invented in 1960 because the holography which is it works on the whole laser. The laser beam is shown in such a way that a 3D object is created, if a person is standing in front of you, it is completely mapped with a laser, then the person who is in front of you with a hologram can be seen in some other place with the help of holograph. The complete 3d image will be created. You must have ever seen a Hollywood movie that there are some robots or characters, they are in the form of light, a hand passes through them, a person passes through them, something seems like a soul is standing, but that soul It does not happen, it is the charisma of science. It is shown by the law of reflection and by turning the laser beam in such a way that as I told you that sound can be recorded, in the same way light can also be recorded. When the light is being reflected by bending in different forms, then only we can see something. If we do all those things artificially in some other place then it will be seen the same things which we have done. It will appear as if a person is actually standing.
But that would be just a play of light.

Now let us talk about what is meant by holography. Holography has come out of a Greek word in which holo means whole and graphy means writing when writing something completely is what Holography is. The photo which is normal, the projector which is 1D, we can see it from one side. That is projected on the screen, that is different. It's a projector
If you play a film in 3D, then the film will be visible from the front, but when you watch it from the side, you will still be able to see the film. You will see the film from the side also, 3D imaging is there. The invention that happened there was in 1947, it was also done by mistake, it was Dennis Gabor, he was working on the electron microscope, but he had invented it. His invention was not so successful because laser was needed to make it work, then in 1960 laser was invented. After that Holography had caught a fast pace and there was a good improvement and then in 1971 Dennis Gabor got the Nobel Prize. The technology they have of electron microscope is used even today.
3D imaging of humans |
So what do we know that what is Holography, by recording any light and showing it in such a way, by using the rules of Reflex, Reflection, to show the light in such a way that someone keeps the object's light and 3D imaging and we We can play it again on the machine, like today a person is 80 years old, we know that after a few years that person will not be in this world, so we can keep his holographic image. After 20, 30, 40 years, when that person will not be human, then we can run Holography image of that person through machines and we will see that person standing like that because we had already taken his imaging, again that person will be seen standing. Too much of a good thing can happen.

Now communication can also change due to this. A revolution can come in communication, how can I tell you that we make video calls, can Holography calls be made? Just imagine if you talk to someone, he will be standing or sitting in front of you and you will be talking face to face, in fact he will be sitting miles away from you, but the one who will be seen sitting in front of us because his holographic image will be being made and This day is also not too far, soon this technology will also come in the coming time and at the same time it can also be useful for meeting. Many times it happens that those who are businessmen are not able to go far and wide in a big country so quickly, in such a case they can attend the meeting sitting at their home.
But they will be seen sitting in some other country and they will also be able to hear and communicate. This is a very good thing. This is the next step of science in communication technology.
now i hope you
