Abstract
A single SLM full-color holographic 3-D display based on sampling and selective frequency-filtering methods is proposed. Sampled R, G and B-holograms provide periodic 3×3 arrays of their frequency spectrums. By allocating three groups of three spectrums to each color hologram, and selectively filtering out those spectrums with their own spectrum filtering masks, frequency-filtered R, G and B-holograms can be obtained. These holograms are then multiplexed into a single hologram and reconstructed into a full-color 3-D image on a 4-f lens system. With the Fourier-optical analysis and experiments with 3-D objects the feasibility of the proposed system is finally confirmed.
