Hologram generation via Hilbert transform
We propose an indirect method for generating a complex hologram and phase-only hologram from an amplitude hologram using the Hilbert transform.

Zusammenfassung: | We propose an indirect method for generating a complex hologram and phase-only hologram from an amplitude hologram using the Hilbert transform. The Hilbert transform generates an imaginary part of complex amplitude from only an amplitude hologram, resulting in the reduction of the total computational complexity of complex and phase-only holograms. More importantly, the proposed method can reduce the hardware resources of dedicated hologram processors. |
