360° display of 3D objects by cylindrical holography.

Cylindrical computer-generated holography (CCGH) has garnered significant attention due to its ability to offer a 360° viewing zone. However, generating a CCGH capable of reconstructing multiple realistic three-dimensional (3D) objects is still a challenge under the constraints of limited computational resources. In this Letter, we introduce a novel, to the best of our knowledge, CCGH generation algorithm that can reconstruct 3D objects within a 360° viewing zone under limited computational resources. The algorithm generates CCGH in segments, which is achieved by calculating the light field distribution of the 3D object on the tangent plane. Numerical simulations and optical experiments validate the effectiveness of our proposed algorithm, demonstrating its superiority in reconstructing realistic 3D objects within a complete 360° viewing zone. This work represents a significant advancement in the practical application of CCGH.
