Silicon holograms harness the full visible spectrum to bring holographic projections one step closer, report scientists. A research team has now demonstrated the hologram of three flat images at wavelengths ranging from blue (480 nanometers) to red (680 nanometers). The images appeared in planes 50 microns apart for red and higher spacings for shorter wavelengths.
