Execution of a single hologram of a photon was previously impossible due to reasons physically fundamental. Researchers from the Physics Department at the University of Warsaw has succeeded, in the original way to move ideas classic holography into the world of quantum phenomena.New measuring technology not only allowed the registration of the first hologram single particles of light, but also allowed in a new way to look at the foundations of quantum mechanics.
The Faculty of Physics of the University of Warsaw (FUW) made the first hologram single particles of light. Spectacular experiment, described in the prestigious journal Nature Photonics”, conducted by Dr. Radosław Chrapkiewicz and mgr Michał Jachura under the direction of Dr. HAB. Wojciech Wasilewski and Prof. Dr. HAB. Konrad Banaszka. Registration of hologram marks the beginning of a new kind of a photon holography: holography, quantum, which reveals a new view on the world of quantum phenomena.
“In a relatively simple experiment we have measured and we saw something that spot is very difficult: the shape of the wave fronts of a single photon”, says Dr. Radosław Chrapkiewicz.
The standard of photography in the individual sections of the image it records only the intensity of the light. In classical holography with the phenomenon of interference saves also a phase of light wave (this is phase brings about the depth of the images).
Execution of the hologram is that well known, an unobstructed light wave (reference) overlaps with a second wave of the same length, but taken from a 3D object (and therefore of the ridges and valleys of the light wave moved in varying degrees at different points in the image).
It comes to interference, that as a result of differences in the stages of both waves creates a complicated fringe. So registered hologram simply light the reference beam to recreate the spatial structure of wave fronts of light reflected from the object, and thus its three-dimensional shape.
