lines of modulated light across a display surface by rotating a scanning element forward from a first to a second position. The right-eye image is formed by providing data for lines of the right-eye image, ordered in sequence from the second to the first edge of the image frame and forming successive lines of modulated light, progressively scanning the lines of modulated light across the display surface by rotating the scanning element in reverse from the second to the first position. The left-eye image is distinguished from the right-eye image.
