散焦

Its well known that both thermal self-defocusing effect and reverse saturable absorption can lead to optical limiting.

众所周知，热自散焦效应和反饱和吸收效应都能导致光限幅。

Always go for final image at focus, not the perfect defocused image for collimating.

我们追求的还是焦点上的图像质量，而不是散焦后的图像质量。

At the same time, the popular culture appearing with the course of modernization exerts the strategies such as conversion focalizing and defocusing etc.

同时随现代化进程而出现的大众文化运用&转换&、&聚焦&、&散焦&等策略展开了对于时间危机的拯救。

To prove our theory, we have done some experiments: 1 observed the focusing and scanning of the longitudinal wave in isotropic solid ; 2 measured the transition process and weighting effect in isotropic solid; 3 observed the focusing of SAW wave on YZ-LiNbO〓 metaled surface and defocusing as deviation from the pure-mode direction.

为了验证理论，本文用声光衍射的方法观察了：(1)各向同性的Fused SiO〓固体中纵波声束的会聚及焦点沿轴线的扫描；(2)表面阵列在Fused SiO〓固体中纵波+1级会聚的过渡现象；(3)YZ-LiN-bO〓金属化表面上表面波在纯模方向的会聚以及对称轴线偏离纯模方向时严重的散焦。

We want to get the scope to go right to a circle from the smallest defocused point without pinching or squishing out one side.

我们希望散焦最小的程度下，衍射圆都是规则的，那么望远镜调教就不错了。

This is just a reminder to show you the effect of GI caustics.

这里只是提示一下GI散焦的影响。

This smaller light will also result in more noticable caustics.

更小的灯将产生更容易令人注意的散焦。

Remember my rambling about GI caustics on page 2 of the materials settings tutorial?

记得Vray材质设置基础里的GI散焦没？

In the GI settings, turn of refractive GI caustics.

在GI设置里，关掉折射GI散焦。

Caustics: The perfect indirect light....

散焦：一个完美的间接光共二十一个
