The impact of this new technology seems like a continuation of the loved Harry Potter series. The ordinary lenses can cover everything that is beside, even in bright daylight. Brace yourself for what is next!
Some prototypes worked only among certain colored lights. But daylight contains a large range of colors. Recently, scientists provide the solution. They invented a spectral invisibility cloak, that covers anything situated under broadband illumination. The results were hosted by Optica, a scientific journal for large-scale innovations.
The opinion of a specialist
“Our work represents a breakthrough in the quest for invisibility cloaking. We have made a target object fully invisible to observation under realistic broadband illumination by propagating the illumination wave through the object with no detectable distortion, exactly as if the object and cloak were not present,” affirms José Azaña, from the National Institute of Scientific Research (INRS) in Montréal, Canada.
The shape of things is given by the light way that encounters objects. In other words, if we can reshape the direction of light, objects are no longer visible for human eye!
A simple how-to
The structure of the device is quick and easy to resemble. It contains one pair of dispersive optical fiber and another of a temporal phase modulator. The first two are set in front and are forcing the broadband colors to pass at various speeds. The ones behind are temporal phase modulators. They transform the optical frequency of light when the light wave travels within the lens. The lenses can be ordered from the internet or buy off a local specialized store.
The possible uses, besides making yourself Harry-Potter
The gadget can be used in future for entertainment, telecommunications, surgeries. But also for information processing and to secure data transmitted with fiber optic lines. The fairy-like spectral cloaking will be able one day to hide objects espied from every direction.
