Simulation of Moire Effect in 3D Displays

Abstract

Theoretical and experimental investigations of moirés in 3D displays were performed. To describe and minimize moirés, we propose the polar representation form of moiré waves. The experimental and theoretical data are in good agreement except in the neighborhood of the minimization angle. The implicit formulas are found for visible moirés of line gratings at finite distances. The computer simulation and the physical experiments confirm the moiré appearance for this case.

Analytical model of multiview autostereoscopic 3D display with a barrier or a lenticular plate

“…Among the possible applications are analyzing regions, image cells, and image mixing; designing autostereoscopic displays (full-parallax and HPO displays with rectangular, hexagonal, and slanted image cells); measurement, analysis, simulation, and control of the geometric characteristics of 3D displays [35,56]; and analyzing the depth and resolution [26]. There can be many other applications (e.g.…”

“…The model has already been applied to the multiview wavelets [36], to the estimation of the image quality [45,55], to the estimation of the probability of the pseudoscopic effect [31], and to the measurements of the geometric characteristics of displays [35] (i.e. the OVD).…”

“…Multiple regions were considered in [31] and [45]. The first necessary condition for multiple regions to exist [46] is that the angular luminosity of the light source should cover the next lateral base:…”

“…A particular advantage of the projective form is in the uniform layout of regions; therefore, wider areas of regions can be observed at once. This makes the model a useful and flexible tool for various practical applications, including for the measurements of the optimal viewing distance (OVD) [35] and the estimation of the image quality [33] and wavelet transform [36].…”

Integral-floating Display with 360 Degree Horizontal Viewing Angle

“…In the reconstruction part, a full-parallax 3D image can be displayed in real-time with different perspectives according to viewing direction from a recorded set of elemental images by using the same lens array. However, reconstructed 3D images have narrow viewing angles limited by the numerical aperture of each lens in the lens array [1][2][3][4][5].…”
