American scientists from the Harvard School of Engineering and Applied Sciences (seas) developed a revolutionary type of light that has changed its shape on flights at different speeds, not only their bending like ordinary optical vortices, but also a revolutionary light – Optical Rotatum ”. The study was published scientifically magazine Science Developments (SCIADV).
The name “Rotatum” is borrowed from the classic mechanics – explains a change in the torque. Unlike standard vortex rays, these light clutches develop along a complex spiral orbit that resemble natural patterns: Nautilus shells, the location of sunflower seeds and even a number of fibonacci.
“This is a completely new light behavior. Not only moves in a spiral, but also transforms in a spiral, but creates unique powers that can control germs,” he said.
The team used metaphors – Ultra fine lenses with nanoyaps to give a controlled polarization and orbit moment to light. The switch breakthrough was the addition of the ability to replace smoothly while spreading the spatial torque of the beam.
It is noteworthy that the effect is obtained using a compact liquid crystal display and a low -density beam, which makes technology more accessible for voluminous laser installations.
According to experts, Torkun will allow you to move colloidal particles and biological examples with unprecedented accuracy, and the simplicity of the design will accelerate the entrance to the industry and laboratory.
Researchers hope that their work will inspire not only physicists, but also to mathematicians to examine universal laws that combine slight vortexes with natural phenomena.
