A filter is defined as removing superfluous or unwanted items. A stereoscopic 3D system can work because only a particular wavelength of light reaches the viewer's eyes, and all other wavelengths of light do not meet the requirements. As a result, the images of 3D glasses are much more dim compared to the 2D version.
Light polarization systems are used in commercial theaters and other high-end applications. These methods provide high quality 3D experience in commercial cinema, while the popularity of digital projectors makes the 3D effect even better. In a polarized light system, light from one or more projections passes through a polarization filter so that all the light waves oscillate in the same direction.
