摘要： Orbital angular momentum (OAM), as a new degree of freedom, has recently been applied in holography technology. Due to the infinite helical mode index of OAM mode, a large number of holographic images can be reconstructed from an OAM-multiplexing hologram. However, the traditional design of an OAM hologram is constrained by the helical mode index of the selected OAM mode, for a larger helical mode index OAM mode has a bigger sampling distance, and the crosstalk is produced for different sampling distances for different OAM modes. In this paper, we present the design of the OAM hologram based on a Bessel—Gaussian beam, which is non-diffractive and has a self-healing property during its propagation. The Fourier transform of the Bessel—Gaussian beam is the perfect vortex mode that has the fixed ring radius for different OAM modes. The results of simulation and experiment have demonstrated the feasibility of the generation of the OAM hologram with the Bessel—Gaussian beam. The quality of the reconstructed holographic image is increased, and the security is enhanced. Additionally, the anti-interference property is improved owing to its self-healing property of the Bessel-OAM holography.

The Fourier transform of the Bessel—Gaussian beam is the perfect vortex mode that has the fixed ring radius for different OAM modes.
