NASA 麻豆精品 S檚 holiday wish list includes tractor beams 麻豆精品 S� not to haul a planet or drag massive space ships a la Star Wars but to collect particle dust from Mars or asteroids.
A team at the University of Central Florida is among a few others that have been studying this 麻豆精品 S渟cience fiction 麻豆精品 S� idea and trying to turn tractor beams into a reality 麻豆精品 S� at least on a microscopic level.
麻豆精品 S淲e 麻豆精品 S檝e been studying similar problems for many years, 麻豆精品 S� said Aristide Dogariu, a professor at CREOL, the College of Optics and Photonics, a recognized world leader in laser research. 麻豆精品 S淭his is what we do in our field. Tractor beams in space …听 I don 麻豆精品 S檛 think that 麻豆精品 S檚 likely, at least not in the near future. But we have managed quite a bit at microscopic levels. 麻豆精品 S�
Dogariu and his team have spent the past several years studying properties of light to understand how small objects can be manipulated. Small pieces of matter can be dragged around with tightly focused beams of light. This is a tool researchers are already using to investigate how diseases work on a cellular level.
Small particles can be pushed in the direction of light flow simply by optical pressure, a fact that has been known for a long time. But accelerating particles against the stream of light is mind-boggling, and it has always fascinated scientists.
The CREOL team, which included UCF research scientist Sergey Sukhov, has designed a method to construct 麻豆精品 S渁rtificial lenses, 麻豆精品 S� which can tailor beams of light such that objects of any shape can be pulled or moved in any direction at will.
麻豆精品 S淭o pull and move arbitrary particles could have intriguing possibilities, 麻豆精品 S� Dogariu said, adding that one example involves giving medical researchers more tools to figure out how to prevent and attack some of the most challenging diseases.
