I also had fun doing the background and setting up the light source.

我也喜欢研究背景和布置光源。

In the simple diagram below, we can see that the light source is coming from the left.

下图中，光源来自左方。

Diffusion scatters light, essentially making the light source broader and therefore softer.

运用漫散射分散光线的实质还是使光源变广，从而达到柔化光线的目的。

Intensity, if we increase the intensity, we're not increasing the energy in each photon, we're just increasing the number of photons that we're shooting out of our laser, whatever our light source is.

强度，如果我们增加强度，我们增加的不是,每个光子的能量，我们增加的仅仅是,从我们激光源射出的光子数，无论我们的光源是什么。

So, we would expect to see electrons ejected with the UV light source.

所以，我们能够预测,可以看到电子被紫外光源射出。

The light source is polarized by a Polarized Beam Splitter and reflects off of each of the chips.

ENGADGET: D-ILA and DLP: what are they? HD

Utilizing a light bulb as the light source, the light is reflected from a small DMD to the screen.

His nanocrystals are not yet quite true lasers since these require that the light source be surrounded by mirrors.
