In Physical Review Letters the group of scientists- Professor David Raffner and Professor David Grier from the University of New York, USA published an article, in which they claim, that they have managed to create Tractor beam using two Bessel beams. As reported by Professor David Raffner and David Grier, if use just two of the Bessel beams with a special lens, that alters the specific direction of propagation of rays, that they overlap in the target, it is the target will move towards the source of light, as there is a strobe effect, when the first light of Bessel beam, which puts pressure on the most distant from the observer plane of the body-target, combined with a second Bessel beam, which presses on the same plane at an angle, resulting in the resultant force is directed towards the source of light, which causes this body-target to move to this source of light. NASA considered three main projects of Tractor Beam, which are going to use to clean up the debris and capture of small asteroids, THE VIDEO:
