A spherical crown diffraction model for curved holographic display is proposed by utilizing occlusion, improving the view angle and optical utilization.
The information of occlusion culling in the spherical holography has been ignored or discarded for a long time. However, the information of the occlusion could be utilized, which has never been considered before. In this paper, a spherical crown diffraction model for a curved holographic display is proposed by occlusion utilizing. In the proposed spherical crown diffraction model, the method of occlusion utilizing is realized firstly, which is based on an optical-path-select function to remain the desired light information. Based on the method of occlusion utilizing, a spherical crown diffraction model for curve holographic display is proposed by further analyzing the optical propagation geometry relationship. This proposed diffraction model not only retains the advantage of a conventional diffraction model with a large view angle of 360 degrees in the azimuth direction, but also improves the view angle in the latitude direction. Besides, the proposed model by occlusion utilizing has higher optical utilization than that model by occlusion culling. Furthermore, the effectiveness and feasibility of the proposed model are verified by numerical simulations. To our knowledge, it is the first time that a method and an application are proposed to utilize the occlusion.
