“…Despite their widespread use in vision research, objective methods for measuring crosstalk across these various systems have been reported relatively rarely (e.g., Woods, 2012; Woods et al, 2010), and typically for lower-performance consumer-focused devices (Weissman & Woods, 2011) rather than systems designed for use in research. Some studies report crosstalk for individual items of research-grade equipment, though it can be difficult to draw comparisons between systems when different methodologies are used across studies.…”

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.

Evidence by numerous papers on stereoscopic crosstalk presented at the Stereoscopic Displays and Applications conference and other display related conferences for the past several years.…”

Liquid Crystal Shutter (LCS) 3D glasses (also known as 3D shutter glasses, active glasses, or just shutter glasses) are the selection device commonly used to view 3D stereoscopic content on time-sequential 3D displays. There are many available models of LCS glasses to choose from; although, unfortunately, there can be wide performance differences between these glasses. Ultimately the perceived quality of 3D image viewing depends on the display viewed as well as the performance of the shutter glasses used. The objective of this paper is to define key glasses performance parameters and to present a testing method to help quantify glasses and select between models available. Differences in shutter opening speed and open transparency (shuttering performance) are shown between tested models using the method presented here. Additional differences are noted for other performance parameters and features illustrating that there can be many product differences to consider that do not directly affect shuttering performance.

“…Various methods exist to evaluate the ghosting in 3D systems as well as techniques of compensation. For example, measures can be done qualitatively using Test Charts [9], or quantitatively using CCD cameras [10]. All of them are based on the same idea: the stereo streams display static images containing a bright zone and a gray scale.…”

In this paper, we discuss various technical options to implement 3D dual-view systems, from four frames generated by two triggered or non-triggered 3D projectors. Such a technique offers 3D free-viewpoint capabilities for two viewers. We compare two different technical implementations based on transmissive video projection and reflective silver screen, combining two different 3D encoding techniques: polarization and time multiplexing. The main objective is to analyze and mitigate the ghosting effects, as a function of the technical, modal and frame pairing choices with respect, first to the image optical quality and second to prevent visual fatigue. We suggest some solutions to reduce the impact of the physical ghosting and frame unbalance. These solutions will be expanded in a second paper.
