三维视觉作为一种常见的成像技术已被广泛使用。3D显示器已经在娱乐、医疗等各个领域投入实际应用。三维显示技术的发展将在广泛的领域发挥重要作用。显示三维图像的方法有多种方法。有一种显示三维图像的方法是利用射线再现法，我们对此进行了重点研究。由于该方法根据不同的视点显示不同的视点图像，因此在实现全视差时需要大量的视点图像。我们建议通过使用旋转镜将投影仪的光线限制在仅观看者周围来减少浪费光线，并提高显示设备的效率，以实现全视差3D显示。我们提出了一种使用跟踪观察者的眼睛，高速投影仪，跟踪观察者的旋转镜（旋转镜），具有不同垂直斜率的凹面镜阵列（凹面镜阵列），圆柱形反射镜的方法。在仿真中，我们确定了射线在水平方向上的扫描范围和运动轨迹。此外，我们确认了视点的切换和光线垂直方向的收敛性能。因此，我们确认了实现全视差是可能的。
The Three-Dimensional (3D) vision became widely known as familiar imaging technique now. The 3D display has been put into practical use in various fields, such as entertainment and medical fields. Development of 3D display technology will play an important role in a wide range of fields. There are various ways to the method of displaying 3D image. There is one of the methods that showing 3D image method to use the ray reproduction and we focused on it. This method needs many viewpoint images when achieve a full-parallax because this method display different viewpoint image depending on the viewpoint. We proposed to reduce wasteful rays by limiting projector’s ray emitted to around only viewer using a spinning mirror, and to increase effectiveness of display device to achieve a full-parallax 3D display. We propose a method by using a tracking viewer’s eye, a high-speed projector, a rotating mirror that tracking viewer (a spinning mirror), a concave mirror array having the different vertical slope arranged circumferentially (a concave mirror array), a cylindrical mirror. About proposed method in simulation, we confirmed the scanning range and the locus of the movement in the horizontal direction of the ray. In addition, we confirmed the switching of the viewpoints and convergence performance in the vertical direction of rays. Therefore, we confirmed that it is possible to realize a full-parallax.
