Discovering the Hidden Significances of Holography in Every Day Life and Our Future World

When you hear the phrase"technology of the future", I'm sure holography does not come to mind. holography is a ery intersesting concept and its uses ar endless. Reaching from communication to health care, thsi technology h as yet to make its mark. Its name comes from the Greek words "holos" meaning "whole", and "gramma" meaning "message". And holography is just that. Well almost, it still has a lot of work to be done.

A Hologram is simply a picture, in three dimensional imaging. It was a first invented in 1947, when a Hungarian scdientistr Dennis Gabor attempted to modify the electron microscope. Unforunately, he was unable to make the light concetrated and allow defined forms to be distinguised. The light sources around at the time were not purely "coherent". By 1960, the invention of the laser came about. This further stemmed the invention of the pulsed ruby laser which would give off a strong burst of light that would allowthings moving at high speeds to be shown as real as possible in holographic forms. In 1967, the first holographic human people were created.

In detail, holography creates a 3-D image when a light source touches the light of a similar wave length coming from an object. That being said, a hologram is almost impossible to decipher when a hologram is only lit up by the initial light source. To make a completed hologram, it must have both components. HJolography is split up into two different types. They are reflections holograms and transmission holograms. A third type is called a hybrid hologram which is special and newer kind of hologram.

Reflection holograms are the most common. They consist of a white incandescent light that is localized into a spot. This spot is put at a certain angle, diustance and put on the observer's side of the object. The visible image uses the reflected light of the hologram. This kind of hologram is used mostly in art galleries. It is also responsible for the cool cards we would tilt different way to catch light and see different images. Life makes sense now, doesn't it?

The other kind of holography is called transmission holography. This one requires a laser light to be located behind the object and transmitted through it. This one is cool because you can put a piece of paper all around the object and still be albe to observe it through a hole. Also, depending on the holes location, you can look at different perspectives of it. This kind of holography is responsible for our projectors and powerpoints. Isn't this a pleasant discovery.

Hybrid holograms are a happy medium of the two. Hybrid holograms include the way we can mass produce holograms by "embossed holograms". This way uses a series of nickel deposits and grooved surfaces to catch the light and produce different images. Another method is the integral holograms. This uses several transparencies that are usually scanned into a camera, then shown on an LCD screen and lit up by a laser to create the hologram. Then holographic interferometry is used to make invisible objects visible, such as shock waves and heat waves.

Holography has made its way into today's life, and has made the world of healthcare even further advanced. For the future surgeons, they now are able to get a little practice in before working on a real body. Holograms make it possible for students to simulate body parts and see how they would operate on them and such. Also, current doctors are able to make three dimensional images of body parts in order to be better able to treat and diagnose injuries and disorders. They are able to simluate bones, eyes, organs, and more. They can also have a more advanced look at cavitites within the body that would be otherwise unseen by x-rays and CT scans.

Holograms are an interesting phenomenon that has taken many years to invent and improve. It is really amazing to think that lasers have such an important function in today's world. We will continue to make further discoveries about this and hopefully one day we can communicate further by using holograms. Such as working from home and being able to attend meetings via holograms. Wouldn't that be a neat convenience? But then again, it would continue to make our society even more lazy. Will this jepordize our existence or make it better? Many questions are out there surrounding the issue, I'm going to go with let's keep working on it and see where it leads us. Every advancement solves a problem, and then creates more to be fixed. If everything was perfect, there would be no reason for us to exist.

Great Job! You have written a great post on the chosen topic. You have brought up great points. I agree, I wonder if someday we will be able to have coffee with other holograms. That would be an interesting experience. I guess we'll just have to wait and see what the future holds for us.

Megan-

Too many typos in the first paragraph. You may want to fix them.

MS. Eder said...

Megan-

Read through your article again. More typos in other paragraphs also.

great post megan, it was really informative. don't worry, the typos really didn't throw me off too much at all. overall, the information was really detailed. I agree with how it will be used so much in our future. NICE freakin' work.

Meg,

I liked the Greek translations. Sometimes they are useless, but in this case, it really explains things. I really liked the interesting fact that it has more used in medicine that I thought. Holograms are a multi-faceted object or whatever.

Fabulous Megan,

I think you may have won the award for best title. It's a close one between you and Hailey though. The typos added an extra original flair to your post lol. Maybe you should consider an editor jk, but your title was flawlessly written.

Nice!
i saw a few typos...but i guess ill let them slip! i agree holograms are extremely interesting. its kind of creepy though that they can re-create people with them...yikes! your post was really well written and i enjoyed reading it. keep up the good work!

HELLO ALL BLOG READERS!

I would like to apologize to all of you that have and are reading my post. As it were, I have noticed that I have had a few typos, and I am truly sorry that between my often thirty hour works weeks and school work, I have made a few minor mistakes on my blog. By the time I am able to post my blogs, I usually am extremely tired and am happy to just be able to post my blog. If this causes you any distress, please let me know and I will do the best I can to aleviate the issue.

Thank your for your utmost understanding,
Megan

Megan,
I really enjoyed your technique of introducing holograms. I also thought you provided a great historical background on the topic. I really liked your detailed descriptions of the different hologram types and its uses in medicine. I agree with the facts you presented in your last paragraph. Technology doesn't always help us and it often creates more problems than those that existed before. You also provided some satire, which increases enjoyment while reading. I liked your unique perspective as usual.
~Lindsey~ :)

That was "terribly" a good post. You had "terribly" good information. And you were "TERRIBLY" correct that holograms are an interesting phenomena. I "terribly" enjoyed your post.

"Terribly" yours,
Dustin

Nice job meggie,

Wow megan that was a really good post. I really enjoyed reading your thoughts and ideas about this topic. You had some spelling errors I must admit:). Other than that it was fun to read. Keep up the good work.
