Stimulus Arrangements for Creating Stereoscopic Displays
Stereoscopic displays present binocular disparity on a display surface that is used for getting images projected onto the left- and right-eye retinas so that depth perception can be induced. To do so, slightly different images must be presented to the two eyes. There are several ways to present different images to the two eyes. The spatial-multiplexing approach involves presenting images to the two eyes so that they are spatially interleaved. This can involve simultaneous left-eye and right-eye presentations by using two regions on one 2D display, with each region seen by only one eye, or by using wavelength-multiplexing techniques. The time-multiplexing, or field-sequential, approach entails presenting images to the left and right eyes so that they are temporally interleaved. This involves having the left-eye and right-eye presentations on alternate frames of the display. The basics of these two approaches are discussed below; for more thorough discussion, see Lueder (2012).
