ILLUSTRATION 5‑16 IMAGE PROJECTION WITH POLARIZATION FILTER - PROYECCIÓN DE IMÁGENES CON FILTROS DE POLARIZACIÓN
These light beams projected to the screen bounces back the spectator's glasses composed of two lenses, a polarizing filter with a vertical and horizontal with a filter, allowing to obtain three-dimensional image.
ILLUSTRATION 5‑17 IMAGE DISPLAY FOR POLARIZED SYSTEMS
The polarized image display system improves the system by not producing anaglyphic alteration of three-dimensional color images, but has other issues such as loss of brightness. To solve this problem should increase the sources of light but this can cause other effects such as ghosting due to the high contrast images.
SEQUENCE FIELD SYSTEM
Sequence Field is the most efficient 3D video display system of the three described.
This system uses a pair of LCD glasses to separate images for each eye, which will be shown sequentially. To accomplish this it is necessary to multiplex the images and the glasses are kept synchronized with the layout of each of the two fields that make up an image, for showing the image on the right pane the left pane is covered and vice versa.
