一个摄像头接受横向偏振光，一个摄像头接受纵向偏振光。
One camera receives horizontally polarized light, while the other receives vertically polarized light.
通过分离横向偏振和纵向偏振，将其叠加生成一幅更准确的指纹图，将此作为计算机处理认证的输入。
By separating the vertical and the horizontal polarization, the device can overlap those images to produce an accurate fingerprint, which is fed to a computer for verification.
利用改进的能流法研究了任意偏振态光束发生全反射时的侧向和横向位移特性。
The lateral and transverse shift of an arbitrarily polarized beam is investigated by the improved energy flux method.
