We’re all used to the plastic 3D glasses we have to wear whenever we attend a 3D film. Up until now that’s been the norm; however, it looks like 3D glasses may soon be a thing of the past.
According to recent articles, advancements have been made on creating 3D screenings without the use of any sort of glasses. CNN explains:
The new method would allow movie theaters to keep their projectors where they’ve always been, behind the audience, and uses fairly simple optical technology. A special array sits in front of the projector and polarizes its light. A filter covering the screen then obscures different vertical regions of the screen, like the slats of venetian blinds. Each of your eyes, sitting at a slightly different angle, has some of the screen blocked and some of the screen visible. The movie has the right-eye and left-eye images interleaved in vertical columns with one another. The trick then is to have the light visible to your left eye contain the left-eye pixels and vice versa for the right eye.
These advancements have been in process ever since the creation of 3D films. We knew one day we’d no longer need 3D glasses, it’s just always been unclear as to when that day would come. There have been many attempts to stimulate a 3D glasses-less experience, by such means as having two movie projectors running simultaneously or by placing the projector directly behind the screen instead of behind the audience. It looks as if these new advancements, now with a better understanding in optics research, may mean not having to shill out a couple extra bucks each time you see a film to afford those damn glasses.
The technology is far from being perfected, and chances are we will not reap the benefits of this progression for many years in the future. Even so, these baby steps are surely a great sign as to where scientists are headed and to what they one day will be able to accomplish.
Just don’t tell the Doctor.
