But at that time, the light pulses could travel only about 20 meters through the glass fibers before 99 percent of the light had dissipated.

但是在那个时候，光脉冲在玻璃光纤中只能穿行20米，99%的光都被损耗了。

The light that is absorbed changes into heat. The car's glass Windows let light in, but don't let all the heat out.

被吸收的光线转换为热能，而汽车的玻璃窗户让阳光进来，却不让热量出去。

We know that UV light gets absorbed by glass, so it shouldn't be able to go through the glass.

我们知道紫外光会被玻璃吸收，所以它无法通过玻璃。

One example the company has developed is a crystal fibre that squeezes light into such a narrow core that the intensity of the light modifies the optical properties of the glass itself.

The bending creates a lensing effect in the same way that light is bent through glass or plastic in a microscope or your eyeglasses.

The light itself comes out of four LEDs that pass through a fiber optic glass designed to distribute the light evenly throughout the screen.
