Overview

Our motivation for building an new Autostereoscopic Display is to give the viewer an new experience when he moves his head around the Display media. This method is by and large inspired by traditional cyclograph photography[1]. Instead of providing Motion and Binocular Parallax, we want the viewer to perceive an rotation effect as if rotating viewing direction around a fix focus axis.

Figure 1 (A) One rotating camera takes pictures of the same fixed object, and we want the viewer to see the similar images as he moves his head around the object. (B/C) The desired image we want the viewer to see when he moves his head to the left or right of the Display

As Figure 1 shows, our method simulates the view of a rotating camera around a static object. When the viewing angle is fixed, the display can give the view of the camera located in a specific direction with respect to the static object. The interesting things happens when viewer gradually changes his viewing direction. What he will see is a rotating object instead of motion parallax in traditional Light Field-based Autostereoscopic Display.

This new three dimensional display could have many useful applications. Especially, in medical imaging, the display of organ or tissue data from CT or MRI scans can provide critical information for doctors to make correct decisions . In practice, the 3D display projects stereo pairs of the object towards any views and it will allow observers to view the object in 3D rather than to view it as 2D images. The multi-lens medical display will also provide motion parallax so that when observers move their head towards left or right, they will instantly see the left side or the right side of the object.
