Full-color holographic 3D display with horizontal full viewing zone by spatiotemporal-division multiplexing
Abstract:
A technical full-color reconstruction method is presented to develop our previous monochromatic holographic three-dimensional display with a horizontal full viewing zone. A digital micromirror device (DMD) is used as a high-speed spatial light modulator, and its modulation area is divided into three parts, which independently handle three sub-holograms corresponding to red, green, and blue components. The reconstructed images from a single frame of the DMD never form full-color images. However, given that this spatial division is combined with the time-division method for the full viewing zone, each monochromatic image is temporally mixed, and practically full-color images are reconstructed. After monochromatic reconstruction from a single frame was confirmed, full-color reconstruction with a horizontal full viewing zone was demonstrated.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
