PART SEVEN: HOLOGRAPHIC CINEMA: A NEW WORLD

Through the reading of Chapter 7, I come to know more about the holography gradually. I think among all the digital techniques today, the Holography is the coolest stuff which can lead a pioneer trend in the future.

Before I start to write about the feedback of part 7, I list a video here for audiences to have a preliminary understanding about the Holographic Cinema.

This is a Burberry fashion show held in Beijing that uses the holographic tech.

In the video, the audiences can clearly see the continuous trace of the models. One can hardly find the source of the light. The models with fashionable suits just show up and disappear magically. This is the fantastic work integrates arts and computer science.

This chapter mainly introduces the invention, development and the future of Holography. The earliest holographic motion pictures really impressed the people. In 1969, Youngblood, who is the author of the article, witnessed the Catholic Monastery, Sierra Retreat showing up at a Research Laboratory. Everyone will be curious about how it was made.

• What is Holography?

Holography is a technique which enables a light field, which is generally the product of a light source scattering off objects, to be recorded and later reconstructed when the original light field is no longer present (due to the absence of the original objects).

The enigma that people concerned about firstly was that there is no optical image formed. Early techniques named wave-front construction created the lensless photography through multi-time experiments. The technology gradually turned to mature and there came out the holographic movie of tropical fish in aquarium, under the effort of scholars from different research labs. That is the first real-time film in the world.

Through hundreds of times experiments, the holography technology today is more complicated and reliable. The computer-generated holographic movies come to rule the markets. Every holographic will be produced and even recorded. People are able to record the holographic of the nature and make it to a movie frame. Movie frame is that you can get your face up so close that the frame disappears and all you're seeing is the illusionistic world on the other side. You're in it.

And this is the contemporary techs, Optical arrangement for reconstructing a hologram.

At last, Gene Youngblood introduces the limitation of Holographic Cinema during the process it developed. To create the perfect holography can one spend a lot of budgets.

I love the way holographic cinema expresses. This tech is really cool and easily accepted accompanied with the beautiful images and music. It can be widely applied to many fields such as commercials, theaters or products Launch. "Someday you'll be able to go to a party and be the only one there." As a whole new world to the audiences, it remains mysterious because it's still not spread to the world. People will definitely get to know it more and more. Holography is the future of projection.
