The principle of 3D movies and 3D eyewear glasses

January 12th, 2010

The 3D movies stimulate people’s passion on 3D eyewear glasses. The 3D movie gives people a novel feeling compared with the traditional 2D movies, which makes you feel like you are involved in that action. Obviously, people are curious about the 3D movies and 3D eyewear glasses novelty and the principle of them.

A brief introduction on the principle of 3D eyewear glasses are given in the following. First of all, we should know the working principle about eyes. Our eyes are spaced about 2 inches apart. Therefore, each eye sees the world from a slightly different perspective, about which you may not realize before. The brain is able to correlate the two eyes’ images even though they are slightly different. The binocular vision system mimics this process by presenting each eyewear glasses with a slightly different image.

In fact, the binocular vision system operates in a very easy action. Taking the play of 3D movie for example, two cameras are needed to photograph the same image from slightly different positions to display on the screen, but the two images are different-colored. A special eyewear glasses are needed, too. The eyewear glasses have the red/green or red/blue system, which means one of your eyewear glasses is red and the other is green or blue. The filters on the eyewear glasses allow only one image to enter each eye, and the rest action is left to the brain. A stereoscopic effect is produced by the feeling of distances-difference.

But the red/green or red/blue eyewear glasses can not provide you with a high quality image because you are using the color to give the separation. So the polarized system is more recommended in 3D effect. In the process of this system, two synchronized projectors project two respective views to the screen with two different vertical polarizations. The eyewear glasses allow each image into each eye because the lenses are also different-polarized.

3D movies, together with the 3D eyewear glasses make you feel excited about the world. Understanding the principle of the 3D effect, you must be surprised about how simple the principle of 3D eyewear glasses is and how amazing the stereoscopic effect shows.
