FREQUENCY COMBS

Full-color holography using combs

Nature Photonics volume 15, pages 866–867 (2021)Cite this article

Subjects

The three-dimensional images generated by digital holography are usually limited to a single color. A new technique exploiting frequency combs generates holograms with hundreds of colors at once.

In 1947, the Hungarian British physicist Dennis Gabor published his groundbreaking work on holography1 that later earned him the 1971 Nobel Prize in Physics. While the original motivation was to improve the resolution of electron microscopes, the ability to record three-dimensional (3D) images using 2D photographs rapidly spread to other fields.
