The principle of 3D imaging

Due to the 4-6 cm (1.6-2.3 inch) separation between the eyes, each eye has a slightly different viewpoint. The images from these two different viewpoints are sent to the brain and this difference, which is termed parallax, is interpreted as depth.

Stereoscopic projection is based on the same principle: two slightly different images are projected onto the screen and the imaging system must enable the left eye to see only the left eye image, and the right eye to see only the right image.

Barco's quality of separation guarantees that the images of the two eyes are separated and displayed in such a way that the final 3D images appear fully focused and not blurred.
