stereoscopic display

In computing, a display which achieves a 3-dimensional (3D) image effect using only one monitor, and a pair of special glasses. The effect is achieved by running the monitor at double the normal frame rate and arranging to show only every other frame to each eye by means of special polarising glasses which black out each eye alternately. This enables each eye to see a normal frame rate image, and the two images differ sufficiently to cause a 3D image to be seen. These kind of displays are used for industrial 3D visualisation, and in 3D cinemas.
