At the moment,marc jacobs there are two kinds of 3D glasses in use which are slave mode and active mode. In slave mode, it divides into 3 types including red-cyan polarized light, linear polarized light and annular polarized light.
The red-cyan polarized light uses principle of colored paper filtering colored light that each side filters red or blue color cast into a image that our eyes could see. As it is difficult to master the movie color, so there are few people to use it.
Another one is linear polarized light. The direction of linear polarized light is 90deg; vertical or 180deg; level, the angle cross of 45deg; and 135deg; is as well while the projector or liquid crystal must be consistent with the glass, or it wonrsquo;t work. And it must use two projectors to make Adobe Dimensions. The polarized light stereo-screen must use silver three-dimensional special screen. The general one can not be available because we can not isolate the two kinds of polarized light. The watching optic angle of linear polarized light three-dimensional system is average which is like 4:3 while the optic angle of right and left is small. As the viewers should wear glsses the cost is so low that it can be wasted, so it is the most ordinary mosel in three-dimensional cinema at the moment.
Annular polarized light is also called circular polarized light which is turning the direction of light left or right.omega speedmaster replica The special pitching optic angle of circular polarized light is small and the relative optic angle of left and right is wide which is suitable for widescreen or plane show space.

The other kind of 3D glass is active mode. In this mode, there is a typical one which is called shutter glasses. It takes advantage of the principle that LCD Filmsrsquo; energization or outage is transparent or dim to make glasses that can switch between left and right. The movie is showed through a digital light processing projector or LCD TV. It needs to set wireless induction to control the switch rate of audiencesrsquo; glasses which should keep consistent with the switch rate of projector.omega replica
