How Do 3D Technology Works ?

                    

Nowadays we come across to the term 3D images many times in a day. We often suppose that, how these 3D images are created & how these images creates an illusion which creates a 3D effect. Below, we have described some techniques to create 3D images.

Before more than 170 years Sir Charles Wheatstone very first experimented the about stereoscopy which is now also known as trick to create 3D images. He gave the principle for it that, both the left & right should be exposed to different images so that the illusion works without changing the strength of original image.

For it, 2 techniques are taken into consideration-

1. Active 3D

2. Passive 3D

1. Active 3D

As these televisions displays full screen images they are supposed to deliver a better quality image than passive 3D devices.

The televisions which include this kind imaging system, 2 different images are exposed to both eyes alternately, very quickly. The 3D glasses contains the shutters which have a smart synchronization with the displayed images on screen. This shutter makes sure that both eyes are looking at different images at same time.

      

2. Passive 3D

Unlike Active 3D these system don’t consists of 2 shutters for different imaging but the 3D glass is filtered so that both eyes sees different images.

The drawback of this kind of 3D imaging is that unlike Active 3D, 2 images are shown same screen at the same time in Passive 3D hence the quality & size of the image is halved & the image is not full HD.

3. 3D without glass

This is the system which the latest companies are opting for 3D imaging. Here the use of glasses is avoided completely & shaped lenticular lenses are used to display different images depending upon the viewing angle.

Companies like Nintendo & Toshiba are using this latest technique in its glass-free 3D television & devices. Moreover the maximum size of these TV is 21 inches till now. Toshiba assures that it will take time to use this technique in larger screen because still using this technique in larger screen is not affordable.
