Retro-reflection based projection 3D display with low crosstalk is proposed. The 3D display consists of a retro-reflective sheet, an image projector array, a vertical scattering layer, and two optical noise sources projectors. The image projector array is used to provide parallax images. The retro-reflective sheet is used to reflect parallax images to different horizontal viewpoints to form 3D images. The vertical scattering layer is used to scatter the reflected light in the vertical directions, and form viewing areas in the vertical projection area of each corresponding projector. The optical noise source projector provides salt and pepper noise to reduce crosstalk. A prototype of the proposed 3D display is developed, and the experiment results agree well with the theory.

提出了一种具有低串扰的基于回射的投影3D显示。3D显示器由回射片，图像投影仪阵列，垂直散射层和两个光学噪声源投影仪组成。图像投影仪阵列用于提供视差图像。逆向反射片用于将视差图像反射到不同的水平视点以形成3D图像。垂直散射层用于在垂直方向上散射反射光，并在每个对应的投影仪的垂直投影区域中形成观察区域。光学噪声源投影仪可提供盐和胡椒粉噪声，以​​减少串扰。开发了所提出的3D显示器的原型，实验结果与理论相吻合。
