A second possibility, for more power-hungry devices, is to fire a finely focused infrared laser beam at a photovoltaic cell, which converts the beam back to electrical energy.
第二种可能性则能应用在更加耗电的设备上。其原理是发射一道精确聚焦的红外激光线,击中光伏电池,由此能够将光束转换回电能。
Tracking twice as many targets as the radar it replaces, the AESA features active electronic beam steering, which allows the radar beam to be repositioned nearly instantaneously.
AESA雷达可以跟踪所替代雷达跟踪数量两倍的目标,可对有源电子波束进行控制,其波束近乎瞬间即可重新配置。
The researchers then narrowed down the X-ray beam so that it was just a tenth of a millimetre across and found that the fractal-like regions occurred only where the beam struck the sample.
研究人员随后将X射线的光束收窄,使其只有十分之一毫米宽,这时他们发现,碎片形的区域只出现在射线照射的地方。
Scientific American magazine says huge lasers turn only about twenty to thirty percent of the energy they use into a laser beam.
