“…Other systems separate the signals either spectrally, temporally, or using light polarization, requiring them to be demultiplexed at the eye, typically using active or passive goggles worn by the participant. Such systems suffer from the problem of crosstalk (or ghosting), where images intended for one eye are also faintly visible to the other eye (e.g., Pan, Lee, Huang, & Huang, 2010; Wang et al, 2011, 2012). In the following, we describe three common methods used for binocular stimulus presentation in a laboratory setting and how crosstalk can arise in these different systems.…”

Studying binocular vision requires precise control over the stimuli presented to the left and right eyes. A popular technique is to segregate signals either temporally (frame interleaving), spectrally (using colored filters), or through light polarization. None of these segregation methods achieves perfect isolation, and so a degree of crosstalk is usually apparent, in which signals intended for one eye are faintly visible to the other eye. Previous studies have reported crosstalk values mostly for consumer-grade systems. Here we measure crosstalk for eight systems, many of which are intended for use in vision research. We provide benchmark crosstalk values, report a negative crosstalk effect in some LCD-based systems, and give guidelines for dealing with crosstalk in different experimental paradigms.

“…Unfortunately comparison of the exact levels of crosstalk in various systems is difficult since crosstalk measurement depends not only on the particular system components but also on the measurement method employed. In general, anaglyph systems have the most crosstalk while time-sequential displays and polarized displays exhibit the least amounts of crosstalk 2,3 .…”

The effect of crosstalk on depth magnitude in thin structures

Stereoscopic displays must present separate images to the viewer's left and right eyes. Crosstalk is the unwanted contamination of one eye's image from the image of the other eye. It has been shown to cause distortions, reduce image quality and visual comfort and increase perceived workload when performing visual tasks. Crosstalk also affects one's ability to perceive stereoscopic depth although little consideration has been given to the perception of depth magnitude in the presence of crosstalk. In this paper we extend a previous study (Tsirlin, Allison & Wilcox, 2010, submitted) on the perception of depth magnitude in stereoscopic occluding and non-occluding surfaces to the special case of crosstalk in thin structures. Crosstalk in thin structures differs qualitatively from that in larger objects due to the separation of the ghost and real images and thus theoretically could have distinct perceptual consequences. To address this question we used a psychophysical paradigm, where observers estimated the perceived depth difference between two thin vertical bars using a measurement scale. Our data show that crosstalk degrades perceived depth. As crosstalk levels increased the magnitude of perceived depth decreased, especially for stimuli with larger relative disparities. In contrast to the effect of crosstalk on depth magnitude in larger objects, in thin structures, a significant detrimental effect was found at all disparities. Our findings, when considered with the other perceptual consequences of crosstalk, suggest that its presence in S3D media even in modest amounts will reduce observers' satisfaction.

“…A more realistic indication of this dependence is given by the increase in the area average crosstalk, its standard deviation, and the maximum crosstalk. Some researchers have suggested other variations of the crosstalk equation to make it more perceptually relevant and have generalized the crosstalk characterization to between gray levels . These alternate formulations can still be represented on a 2D uniformity map and summarized in a manner similar to Table .…”

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.
