Abstract
- The article discusses the modes of projecting 3-D movies in digital format. Z-filter by Real D of Beverly Hills, California, utilizes a liquid-crystal panel that polarizes the light output, while a computer puts into synchronization the switching polarity of the liquid-crystal panel with alternating images. Active glass by International DisplayWorks, Roseville, California utilizes glasses whereby each lens is a liquid-crystal shutter. An infrared signal coming from the projector signals the shutters when to switch to direct the image to the proper eye.
