激光,由于其具有独特的光效应,因而逐渐成为战场上作战的“多面手”。军事通信的“大哥大”。激光以其独有的频率单一、方向性好、保密性强、不受热核辐射干扰等特点,而大受军事通信的青睐。它的信息容量大得惊人,一束激光可容纳上百亿路电话同时通话;若用来传送电视节目,可同时播送1000万套电视节目,这是以往任何通信系统都无法与之相比的,是通信技术上的一次伟大革命。目
Laser, because of its unique optical effect, has gradually become the “multi-faceted” combatant on the battlefield. Military communications “big brother.” Laser with its unique frequency of a single, good direction, confidentiality, from thermal radiation and other characteristics, but greatly favored by military communications. Its information capacity is staggering. A laser beam can hold tens of billions of phone calls at the same time. If it is used to transmit TV programs, it can simultaneously broadcast 10 million TV programs, which can not be compared with any previous communication system Is a great revolution in communications technology.
