Dual comb hyperspectral digital holography 1080p

Everybody has seen holograms, on a bank note, a passport or in Star Wars. Holography is a powerful technique of photography of a light field without a lens for 3D imaging and display. Now, scientists at the Max-Planck Institute of Quantum Optics move holography forward by implementing it with optical frequency combs. Thousands of holograms over all colors of the rainbow can be recorded. By digital processing, each hologram provides a 3-dimensional image of the scene, where the focusing distance can be chosen at will. Combining all these holograms renders the geometrical shape of the 3-dimensional object with very high precision and without ambiguity. At the same time, other diagnostics can be performed by the frequency combs.
