I. Introduction
The techniques of three dimensional (3D) display have been studied for many years with various approaches to display mechanism and screen designs [1], [2]. 3D display system transmits slightly different images to the observers' two eyes to mimic a parallax perceived by human visual system, hence produces 3D illusions [3]. The volumetric 3D displays [4], [5], multiview (or light field) 3D display [6], [7] are emerging approaches. However, most existing commercial 3D display products, such as 3D TV, are still based on lenticular lens array technology [8]– [10], which facilitates large size screens. Therefore, improvement on the lenticular display technology [11]– [13] could impose significant impact upon 3D technology applications and 3D products [14]. In addition, the real-time 3D image-generated is of great significance to medical research field such as augmented reality surgical navigation [15].
