space-charge optics

Photonic lattices are a kind of minuteness optics dielectric structure which its space measure is on the level of the wavelength of light-wave.

光子晶格是介电结构在空间尺度上的周期性光学微结构，它的周期是光波长数量级的，其主要的特性是存在光子带隙。

Finally, did you know that Einstein made TV, nuclear power, fiber optics, space travel, electric eyes, and GPS possible, and also made black holes and the big bang theory understood.

还有，你知道吗，爱因斯坦使得电视、原子弹、光纤、空间旅游、电子眼和全球定位成为可能。还有，他使得宇宙黑洞和宇宙大爆炸理论被人理解。

The Motion capture technology based on optics has attracted more and more attention. But the precision and speed in converting from the marker space position to human motion parameters is still a problem, in which estimating the center of the joint rotation is the key duty.

基于光学的运动捕捉越来越受到人们的重视，但是将捕捉到的Marker点空间位置转换成为人体运动参数的精确性和快速性还是问题，其中关节中心的估算是问题的关键。
