您要查找的是不是：
- rotating polarizing filter 旋转式偏振滤光片
- They then placed a polarizing filter over a ball-rolling beetle to turn its light through 90o. 然后他们在一只滚动球的甲虫上放置一偏振片将光转向90o角。
- With no liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer. 没有液晶之间的偏振滤镜，光线穿过的第一个过滤器将被封锁，由第二（跨过）偏振片。

- Unsafe filters include color film, some non-silver black and white film, medical x-ray films with images on them, smoked glass, photographic neutral density filters and polarizing filters. 任何彩色负片、不含银的黑白负片、被烟熏黑的或用墨汁涂黑玻璃片、太阳眼镜、拍摄用中性减光滤镜、偏振镜、磁盘、光盘等，都是不安全的，肉眼看不见的光线（比如红外线）可能大量穿透这些物品，长时间观看会对眼睛造成很大伤害，因此请不要使用这些替代品进行观日。专业的日食观测镜请到专业可信赖的机构购买。
