The tiny gaps between the tubes collect and trap background light to prevent it from reflecting off surfaces and interfering with the light that scientists actually want to measure.

碳纳米管之间的微小空隙收集并抑制了背景光，阻止这些光线反射出表面，干扰了科学家真正想要测量的光线。

For example, insects can see polarised light - light to them appears as different colours, depending on the Angle at which reflects off different surfaces.

例如，昆虫能够看到极光——光对它们来讲会根据从不同的表面反射的不同角度而显现出不同的颜色。
