Crosstalk, also known as ghosting or leakage, is a primary factor in determining the image quality of stereoscopic three dimensional (3D) displays. In a stereoscopic display, a separate perspective view is presented to each of the observer's two eyes in order to experience a 3D image with depth sensation. When crosstalk is present in a stereoscopic display, each eye will see a combination of the image intended for that eye, and some of the image intended for the other eye-making the image look doubled or ghosted. High levels of crosstalk can make stereoscopic images hard to fuse and lack fidelity, so it is important to achieve low levels of crosstalk in the development of high-quality stereoscopic displays. Descriptive and mathematical definitions of these terms are formalized and summarized. The mechanisms by which crosstalk occurs in different stereoscopic display technologies are also reviewed, including micropol 3D liquid crystal displays (LCDs), autostereoscopic (lenticular and parallax barrier), polarized projection, anaglyph, and time-sequential 3D on LCDs, plasma display panels and cathode ray tubes. Crosstalk reduction and crosstalk cancellation are also discussed along with methods of measuring and simulating crosstalk.

An array detector was employed to characterize the crosstalk and contrast ratio uniformity of three‐dimensional (3D) displays. The measurement method is described and demonstrated on a stereoscopic display with passive glasses. The resulting high resolution spatial uniformity maps enable a comprehensive statistical characterization of the display and provide a useful visual assessment tool. The statistical uniformity data are used to evaluate the crosstalk dependence on viewing conditions (such as viewing distance), and show the degradation in display performance that could not be captured with a discrete spot measurement. The measurement method was also employed to examine the influence of crosstalk on contrast ratio. It is shown that for some 3D displays, the crosstalk uniformity can dominate the perceived contrast. A metric is proposed that defines the maximal crosstalk contribution to the perceived contrast for 3D images with small features. The summary parameters extracted from the uniformity maps can be utilized to define the boundary viewing conditions needed to maintain minimum image quality.
