“…The method reported above is an adaptation of the method already proposed for auto-stereoscopic 3D displays in the conference of last year [2]. For the viewing angle measurements, the experimental constraints are nevertheless different.…”

“…The square maintains the dimension of the quantity as a contrast which can be compared to the standard contrast of displays. These calculations are very similar to those applied to auto-stereoscopic 3D displays but each contrast is obtained separately using the two GL and GR filters [1][2][3]. When different locations are analyzed simultaneously, the different contrasts for each eye are calculated using previous equations, and the minimum value of these contrasts for the different locations is taken using: …”

“…The situation is similar for the auto-stereoscopic 3D displays. Recently we have proposed a new characterization method for auto-stereoscopic 3D displays based on ultrahigh angular resolution Fourier optics measurement and computation in the observer space [1][2][3]. This method is particularly efficient and provides quantitative parameters for easy comparison of auto-stereoscopic 3D displays by computing Qualified Monocular Viewing Space (QMVS) and Qualified Binocular Viewing Space (QBVS), 3D contrast, standard contrast and color shifts.…”

In this paper we propose a method to characterize polarization based stereoscopic 3D displays using multispectral Fourier optics viewing angle measurements. Full polarization analysis of the light emitted by the display in the full viewing cone is made at 31 wavelengths in the visible range. Vertical modulation of the polarization state is observed and explained by the position of the phase shift filter into the display structure. In addition, strong spectral dependence of the ellipticity and polarization degree is observed. These features come from the strong spectral dependence of the phase shift film and introduce some imperfections (color shifts and reduced contrast). Using the measured transmission properties of the two glasses filters, the resulting luminance across each filter is computed for left and right eye views. Monocular contrast for each eye and binocular contrasts are performed in the observer space, and Qualified Monocular and Binocular Viewing Spaces (QMVS and QBVS) can be deduced in the same way as auto-stereoscopic 3D displays allowing direct comparison of the performances.

“…Although the VCMaster3D is placed at 1.5 cm, these four measurements of the angular luminance allow the contrast associated with each eye to be estimated and allow the distribution of light to be calculated at a particular position for the left view, right view, and 3D contrast (the distribution of the 3D autostereoscopic effect). The angular contrast for each view is [28] where YBW is the luminance of the black-white image in the polar coordinates determined by 6, <p, and so on. The employed equations are the inverse of the crosstalk equation; however, this measure is standard in display applications.…”

Abstract-In recent years, many experimental and theoretical research groups worldwide have actively worked on demonstrating the use of liquid crystals (LCs) as adaptive lenses for image generation, waveform shaping, and non-mechanical focusing applications. In particular, important achievements have concerned the development of alternative solutions for 3D vision. This work focuses on the design and evaluation of the electro-optic response of a LC-based 2D/3D autostereoscopic display prototype. A strategy for achieving 2D/3D vision has been implemented with a cylindrical LC lens array placed in front of a display; this array acts as a lenticular sheet with a tunable focal length by electrically controlling the birefringence. The performance of the 2D/3D device was evaluated in terms of the angular luminance, image deflection, crosstalk, and 3D contrast within a simulated environment. These measurements were performed with characterization equipment for autostereoscopic 3D displays (angular resolution of 0.03°).
