近日,美国航天局成功利用激光束将名画《蒙娜丽莎的微笑》传输到绕月飞行的“月球勘测轨道飞行器(LRO)”上。这也是人类首次利用激光在星际间进行图像数据传输。美国航天局称,以上研究是该局利用LRO进行激光通信试验的一部分。通常飞离地球的航天器都是利用无线电通信,LRO是目前唯一绕其他星球飞行且能使用激光通信的航天器。这幅名画首先被数字编码并分解为152×200个像素;而后每个 Recently, NASA successfully used the laser beam to transmit the famous Mona Lisa’s smile to the Lunar Reconnaissance Orbiter (LRO) flying around the moon. This is also the first human use of laser in the interstellar image data transmission. NASA said the study was part of the agency’s LRO laser communications test. Often spacecraft flying off Earth use radio communications. LRO is currently the only spacecraft that can fly around other planets and can use laser communications. The painting was first digitally coded and resolved into 152 × 200 pixels; then each one
