双语：亦真亦幻 初音未来演唱会背后的高科技

点此解咒

Hatsune Miku, a digital avatar created with the help of hologram technology, has become popular all over the world. She held her concert in Shanghai on June 27 and 28 this summer.

初音未来，由全息摄影技术打造的数字化身，现已风靡全球。6月27-28日，她在上海举办了演唱会。

Thousands flocked to Shanghai last month to watch their favorite blue-haired songstress perform live. Looks, however, can be deceiving.

上个月，上千名歌迷涌入上海，只为一睹这位蓝发女歌手现场表演的风采。然而，眼见可不一定为实哦。

The singer, Hatsune Miku, was what some call a digital avatar. Wearing her hair in two long ponytails, Miku appears onstage as a 3-D projection with the help of hologram technology. She sings and dances according to the directions of programmers who choreograph the concerts weeks or months in advance. Developed by Japanese company Crypton Future Media in 2007, this 16-year-old star’s voice is produced by synthesizing software.

初音未来是数字化身的歌手。她扎着两个长长的马尾辫，在全息摄影技术的支持下，以3D形象现身舞台。她根据程序员在演唱会几周甚至几个月前设计的舞蹈动作指令，进行歌唱和舞蹈表演。初音未来由日本Crypton Future Media公司于2007年开发而成。这位明星芳龄二八，声音则是由合成软件制作的。

Holograms, a photographic recording of a light field, can display a three-dimensional image of a subject. Experts take the likenesses and voice of an artist and digitally recreate it through the technology.

全息摄影技术，是对于光场（light field）的摄影记录，可以呈现出物体的三维图像。专业人士先获取某位艺术家的肖像以及声音，然后再通过全息技术手段进行数字化再创造。

Holograms have been used to bring dead celebrities back to life on more than one occasion. In 2012, US hip-hop icon Tupac Shakur reappeared onstage at the Coachella Valley music festival and performed alongside rappers Snoop Dogg and Dr Dre. The audience was shocked and went dead silent. After all, 15 years have passed since Shakur’s death.

全息摄影技术不止一次地被用于呈现过世名人的音容相貌。2012年，美国嘻哈界的偶像人物Tupac（Tupac Shakur，1996年身亡）在科契拉谷音乐节上再次亮相，
