초록
An optical reconstruction of a complex hologram by use of an amplitude-only spatial light modulator (SLM) and phase-only SLM is presented. The complex hologram of diffusively reflective object recorded by optical scanning holography (OSH) is converted to an off-axis hologram to eliminate twin image and background noise. With respect to holographic luminance contrast ratio, the optical reconstructed holographic image from amplitude-only SLM is superior to one from phase-only SLM as well as achieving the same result in numerical reconstruction.
