一束由发光二极管发射出的红外线光立刻进入到使用者眼前的空间，这样一个小型摄像机装置，可分析人们的手势轨迹。

A ring of LEDs projects infrared light into the space immediately in front of the user so a camera in the device can interpret gestures.

这些电梯由地面发射的激光束驱动，接收装置则是位于机械上的光伏单位——正如太阳能电池板中使用的一样——而这个过程被称做“能量束驱动”（power beaming）。

They are powered by laser beams on the ground firing at photovoltaic cells on the vehicles – like those used in solar panels – in a process called “power beaming”.

实测了神光装置中激光系统末级输出能量、激光系统前部和中部定点发射能量及激光系统放大的自发辐射能量。

We have measured the energy outputs from the final stage and from the front and middle stages of this system, as well as the energy of amplified spontaneous emission from the system.
