How Does 3D TV Work?

Many people these days are waiting with bated breath for the new line of 3D TV sets to hit the market. Although there are still some improvements left to be made with this technology for it to be able to replace regular television sets in people’s homes, there is hope that in time there will be a change for the better. Although the switch over from 2D to 3D will be interesting, people will be looking forward to better image quality that the 3D television sets provide at the moment and which cannot replace the high definition image quality of HDTV.
Some technological progress in the camera technology was what originally brought about three dimensional imaging to the viewer. There are three fundamental methods on which the 3D TV can be based. The first is lenticular viewing, the second is the passive glass system and the third is active glass systems. Lenticular viewing does not require the viewer to wear glasses because it is the television screen that incorporates the lenses. These lenses emulate a 3D effect by producing a different image for both eyes. This will create a depth discerning process in your eyes known as stereopsis which allows a 3D image to be formed.
The passive glass system based 3D TV works with the help of glasses which are traditionally used to view 3D movies. The polarized glasses are made to view the overlapping images on the television set. The active glass system also makes use of glasses for viewing but in this case the glasses are doing the work by converting the regular images into 3D. This kind of television can also be used for both 2D and 3D viewing. This is perfect if the viewer wishes to use the 2D benefits of the television as well. The glasses used in this case though, are pretty expensive and that is one of the obstacles in the acceptance of this technology by consumers.
