The crosstalk noise produced in the multiplexing technology of curved computer-generated holograms has caused great damage to reconstructed objects. In order to solve this problem, we propose a method to realize three-dimensional object reconstruction with low crosstalk noise impact. By multiplexing the spherical holograms in the horizontal and vertical directions, the complex amplitudes of the multiple spherical holograms with different curvatures are added to form a composed hologram. The generated hologram records many unrelated scenes of the object. According to the different angles used to generate the hologram, the original object under different viewpoints can be rebuilt, and the multiview multiplexing and reconstruction of three-dimensional objects can be realized. Simulation and optical experiments verify the feasibility of this method.
弯曲计算全息图复用技术中产生的串扰噪声对重建物体造成了极大损害。为解决这一问题，我们提出一种实现低串扰噪声影响的三维物体重建方法。通过在水平和垂直方向复用球面全息图，将不同曲率的多个球面全息图的复振幅相加形成合成全息图。生成的全息图记录了物体的许多不相关场景。根据用于生成全息图的不同角度，可以重建不同视角下的原始物体，从而实现三维物体的多视角复用与重建。仿真和光学实验验证了该方法的可行性。
