2测量偏振的“小蜜蜂”宇宙天体中电磁波具有四项基本性质:时间,能量,方向和偏振,关于偏振可以简单地理解为光在传播过程中振动的方向。无偏(即偏振方向分布在各个方向)的电磁波经过偏振过滤片后得到偏振光(图6)。伽玛暴发出的伽玛射线也是电磁波,伽玛射线的偏振就是电磁波电场的振动方向。我们看3D电影时,屏幕上发出的光经过3D眼镜的左右镜片变成了图像略有不同的两种偏振光,经过我们左右眼的叠加处理就变成了立体的图
2 Measurement of Polarized “Bee ” The universe has four basic properties of electromagnetic waves: time, energy, direction and polarization, which can be simply understood as the direction of vibration of light during propagation. The unpolarized (that is, the polarization directions are distributed in all directions) electromagnetic waves pass through the polarizing filter to obtain polarized light (FIG. 6). The gamma rays emitted by the gamma burst are also electromagnetic waves. The polarization of the gamma rays is the vibration direction of the electromagnetic wave electric field. When we watch a 3D movie, the light emitted by the screen passes through the left and right lenses of the 3D glasses into two polarized lights with slightly different images, and the three-dimensional figure
