摘要: Among the important features of holographic displays are wide viewing angles and full color reconstructed images. The present work focuses on achievement both features. We propose an increased-viewing-angle full-color display using two tiled phase-only spatial light modulators (SLMs), a 4f concave mirrors system, temporal-spatial multiplexing method. optical system consists serves to increase angle. A synchronization control (TSMSC) method is developed achieve image remove crosstalk image. calculate RGB holograms computer-generated pyramid by slice-based Fresnel diffraction algorithm. experimental results indicate that proposed feasible reconstruct 3D with angle 12.8°, which about 3.8 times wider than formed single SLM.
