“…像质量评价方法 [4] 的研究也为动态图像质量的提升提供了参考。近年来，立体(3D)显示技术发展迅速 [5][6][7][8][9][10] ，已经逐步进入各个应用领域。基于双目视差的立体显示由于技术比较成熟，应用最为广泛，主要是偏振式和快门式立体显示，而这两种立体显示技术也多基于成熟的液晶显示器，因此运动模糊成为继串扰后又一影响立体显示图像质量的重要因素 [11] 。本文基于平面运动模糊评价方法和立体显示视觉感知实验提出了基于双目视差的立体显示运动模糊评价方法，客观评价立体显示运动图像质量的同时为质量的提高提供参考。…”

To evaluate the motion image quality of binocular parallax based stereoscopic displays more objectively and precisely, the evaluation method is established based on two dimensional (2D) motion blur evaluation model and three dimensional (3D) perception experiment. The 2D motion blur simulation is applied on the binocular parallax images, and then displayed on the 3D space. After that, the comparison perception experiment is completed between real motion blur perception and simulation. The experiment result shows that factor"parallax"has no significant effect on motion blur perception. Based on these, the average motion blur level of two parallax images is used to establish objective motion blur evaluation method of binocular parallax based stereoscopic displays. The proposed method makes the motion image quality evaluation of binocular parallax based stereoscopic displays more objective and precise. Meanwhile, it provides reference for the motion image quality improvement in stereoscopic displays.

The major challenges in traditional color phase hologram generation are the time-consuming iterative procedure and aberration caused by different wavelengths in color holographic display. Based on the original non-iterative phase hologram generation method-optimized random phase (ORAP), combined with the physical limitations of color holographic display, this paper proposes a full-support optimized random phase (FS-ORAP) method for non-iterative color phase hologram generation. FS-ORAP breaks through the limitation of the original ORAP method in the fixed support constraint of the target amplitude in the spatial domain, the full support constraint can be used to generate phase holograms of target amplitudes with arbitrary support size, which fits well with the generation mode of the three-color channel of the color phase hologram. In addition, the color aberration of the reconstructed image is eliminated by scaling the size of the three-color component. At the same time, FS-ORAP is used for the non-iterative fast generation of three-color channel holograms, which can greatly improve the generation speed of color phase holograms and can be adapted to various color holographic display techniques. Experimental results verify the feasibility of our proposed method.

Holographic three-dimensional (3D) display is a true 3D display technique, which can provide realistic image of a real object or a scene because holography has the ability to reconstruct both the intensity and phase information, i.e., the wave front of the object or scene. Therefore, it could allow the observers to perceive the light as it is scattered by the real object itself without any special eyewear, which is quite different from other 3D display techniques, such as stereoscopic displays and volumetric 3D displays. In this paper, the achievements and developments of the latest new holographic 3D displays are presented. Holographic 3D displays can be divided into static holographic 3D displays and dynamic holographic 3D displays. Here, we briefly introduce the principle of holographic 3D display technique and static holographic 3D displays, and focus on dynamic holographic 3D displays. Large-size, high-resolution and color static holographic 3D displays have already been successfully fabricated and applied in some areas, such as holographic 3D maps and holographic 3D images. However, dynamic holographic 3D displays based on both optical materials and spatial light modulators (SLMs) are still under research, which is a challenge to their applications. Some holographic researchers study the holographic 3D displays based on the SLMs for large-size and large view angle display, but it is difficult to realize them because of limitations of SLMs and there still needs much effort to solve these problems in SLMs. Other holographic researchers work on dynamic holographic materials, such as inorganic crystals, photorefractive polymer, photochromic material etc. The response time and diffraction efficiency are key factors to these materials. Compared with other holographic media, liquid crystals with super-fast response time (about 1 ms) have been reported, which makes it possible to realize video refresh-rate holographic displays. The achievements of dynamic holography, which are helpful for holographic 3D video applications, are presented. Recently, real-time dynamic holographic display has been obtained in super-fast response liquid crystal films, which makes it possible that large-size, high-definition, color holographic 3D video displayers are developed by using these liquid crystal films in the future.
